The CLI prints raw errors from the underlying libraries, which is not ideal for the end-user. Errors should be caught, and user-friendly messages should be displayed, while the technical details are logged for debugging. + +- **Consistent error format?** + - The format is consistent in that it's whatever Go's `error.Error()` method returns.

Some errors have context (e.g., `trix.Decode` wraps `ErrInvalidMagicNumber`), but this is inconsistent. The `fmt.Errorf("%w: message", err)` pattern should be used more widely to provide better context. + +- **Performance metrics?** + - Nothing is currently logged. + +### What Should NOT be Logged + +The application currently does not log anything, so there is no risk of logging sensitive information.

A structured logging library (like `logrus` or the standard library's `slog`) should be introduced in `cmd/trix`. This would allow for different log levels (e.g., controlled by a `--verbose` flag) and provide better insight into the application's behavior, especially during failures.

Validation Gaps Found + +The audit identified the following gaps in the current input validation mechanisms. + +### Gap 1: Unstructured JSON Header Parsing (DoS/Type Confusion) +- **Vulnerability**: The `trix.Decode` function parses the JSON header into a `map[string]interface{}`. This provides no structure or type safety. An attacker can craft a header with unexpected data types (e.g., an array instead of a string for `checksum_algo`). +- **Impact**: Subsequent code that performs type assertions on these map values (e.g., `header["encrypted"].(bool)`) will panic if the type is incorrect, leading to a **Denial of Service (DoS)**. + +### Gap 2: Resource Exhaustion via Gzip Decompression (Decompression Bomb) +- **Vulnerability**: The `enchantrix.GzipSigil.Out` method reads the entire decompressed stream into memory without any limits (`io.ReadAll(r)`). +- **Impact**: An attacker can create a small, highly-compressed file (a "decompression bomb") that, when decompressed, expands to an extremely large size. This will exhaust all available memory, causing a **Denial of Service (DoS)**. + +### Gap 3: Insufficient Validation on File Paths +- **Vulnerability**: The CLI tool accepts file paths via the `--input` and `--output` flags. There is no validation to prevent path traversal attacks (`../../..`). +- **Impact**: While the immediate risk is low since the tool is user-run, if it were ever used in an automated or server-side context, an attacker could potentially read or overwrite arbitrary files on the system. + +### Gap 4: Information Leak in Error Messages +- **Vulnerability**: The error message for an invalid magic number in `trix.Decode` reveals both the expected and received values (`fmt.Errorf("%w: expected %s, got %s", ...)`). +- **Impact**: This provides minor but unnecessary information to an attacker about the file format's internal structure. + +--- + +## 3. Injection Vectors Discovered + +Based on the identified gaps, the following injection vectors exist: + +- **DoS via Malformed Header**: Craft a `.trix` file with a JSON header containing invalid value types for keys like `encrypted` or `checksum_algo`. When the `trix` CLI or any service using `trix.Decode` attempts to process this file, it will crash. +- **DoS via Decompression Bomb**: Craft a compressed `.trix` file using the `gzip` sigil. Feed this file to the `trix decode gzip` command. The process will consume excessive memory and crash. +- **Path Traversal**: While not an "injection" in the traditional sense, providing an output path like `/etc/passwd` to the `trix encode` command on a system with improper permissions could lead to file corruption. + +--- + +## 4. Remediation Recommendations + +The following actions are recommended to close the identified validation gaps. + +### a. Remediate Unstructured JSON Header +- **Recommendation**: Replace the `map[string]interface{}` with a strictly-typed `Header` struct. Use this struct as the target for `json.Unmarshal`. This enforces schema validation at the parsing stage. +- **Code Example (`pkg/trix/trix.go`)**: + +```go +// Create a new Header struct +type Header struct { + Checksum string `json:"checksum,omitempty"` + ChecksumAlgo string `json:"checksum_algo,omitempty"` + Encrypted bool `json:"encrypted,omitempty"` + // Add other expected header fields here... +} + +// Update the Trix struct +type Trix struct { + Header Header // Use the struct instead of map + Payload []byte + // ... rest of the struct +} + +// In trix.Decode function: +// ... +var header Header // Use the new struct type +if err := json.Unmarshal(headerBytes, &header); err != nil { + return nil, err // Let the JSON parser handle validation +} +// ... +``` + +### b. Remediate Gzip Decompression Bomb +- **Recommendation**: Use an `io.LimitedReader` to restrict the amount of data that can be read from the gzip stream, preventing memory exhaustion. +- **Code Example (`pkg/enchantrix/sigils.go`)**: + +```go +// In GzipSigil.Out method: +func (s *GzipSigil) Out(data []byte) ([]byte, error) { + if data == nil { + return nil, nil + } + r, err := gzip.NewReader(bytes.NewReader(data)) + if err != nil { + return nil, err + } + defer r.Close() + + // Limit the output to a reasonable size, e.g., 32MB + const maxDecompressedSize = 32 * 1024 * 1024 + limitedReader := &io.LimitedReader{R: r, N: maxDecompressedSize} + + decompressedData, err := io.ReadAll(limitedReader) + if err != nil { + return nil, err + } + + // Check if the limit was reached + if limitedReader.N == 0 { + return nil, errors.New("enchantrix: decompressed data exceeds size limit") + } + + return decompressedData, nil +} +``` + +### c. Remediate Path Traversal +- **Recommendation**: Before using file paths from user input, they should be cleaned and validated to ensure they are not malicious. At a minimum, use `filepath.Clean`. For stronger security, ensure the resolved path is within an expected base directory. +- **Code Example (`cmd/trix/main.go`)**: + +```go +import "path/filepath" + +func handleEncode(cmd *cobra.Command, inputFile, outputFile, ... + // ... + // Clean the output path + safeOutputFile := filepath.Clean(outputFile) + if outputFile != "" && safeOutputFile != outputFile { + return fmt.Errorf("invalid output path") + } + // Use safeOutputFile for writing + return ioutil.WriteFile(safeOutputFile, encoded, 0644) +} +``` +*(Apply similar logic to all file handling functions)* + +### d. Remediate Leaky Error Messages +- **Recommendation**: Make error messages less specific to external users. +- **Code Example (`pkg/trix/trix.go`)**: + +```go +// In trix.Decode function +if string(magic) != magicNumber { + // OLD: return nil, fmt.Errorf("%w: expected %s, got %s", ErrInvalidMagicNumber, magicNumber, string(magic)) + // NEW: + return nil, ErrInvalidMagicNumber +} +``` From 4a362a44caa0f810cc60e92b8b3e43a15bfb4fe4 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Mon, 2 Feb 2026 01:12:34 +0000 Subject: [PATCH 05/15] feat: add OWASP Top 10 security audit report This commit adds a new file, AUDIT-OWASP.md, which contains a comprehensive security audit of the codebase based on the OWASP Top 10 vulnerabilities.

Long Methods in `pkg/trix/trix.go` + +**Finding:** The `Encode` and `Decode` functions in `pkg/trix/trix.go` are both long methods that handle multiple responsibilities. This increases their cognitive complexity and makes them harder to test and maintain. + +**`Encode` function responsibilities:** +* Validating the magic number. +* Calculating and adding a checksum. +* Serializing the header to JSON. +* Writing the magic number, version, header length, header, and payload to a writer. + +**`Decode` function responsibilities:** +* Validating the magic number. +* Reading and verifying the magic number and version. +* Reading and validating the header length. +* Deserializing the header from JSON. +* Reading the payload. +* Verifying the checksum. + +**Recommendation:** Decompose these methods into smaller, private helper functions, each with a single responsibility. + +**Refactoring Approach (`Encode`):** + +Create helper functions for handling the checksum and writing the components of the `.trix` file. + +**Proposed Helper Functions for `Encode`:** +```go +func (t *Trix) addChecksum() { + if t.ChecksumAlgo != "" { + checksum := crypt.NewService().Hash(t.ChecksumAlgo, string(t.Payload)) + t.Header["checksum"] = checksum + t.Header["checksum_algo"] = string(t.ChecksumAlgo) + } +} + +func writeTrixComponents(w io.Writer, magicNumber string, headerBytes, payload []byte) error { + if _, err := io.WriteString(w, magicNumber); err != nil { + return err + } + if _, err := w.Write([]byte{byte(Version)}); err != nil { + return err + } + if err := binary.Write(w, binary.BigEndian, uint32(len(headerBytes))); err != nil { + return err + } + if _, err := w.Write(headerBytes); err != nil { + return err + } + if _, err := w.Write(payload); err != nil { + return err + } + return nil +} +``` + +**Refactored `Encode` function:** +```go +func Encode(trix *Trix, magicNumber string, w io.Writer) ([]byte, error) { + if len(magicNumber) != 4 { + return nil, ErrMagicNumberLength + } + + trix.addChecksum() + + headerBytes, err := json.Marshal(trix.Header) + if err != nil { + return nil, err + } + + var buf *bytes.Buffer + writer := w + if writer == nil { + buf = new(bytes.Buffer) + writer = buf + } + + if err := writeTrixComponents(writer, magicNumber, headerBytes, trix.Payload); err != nil { + return nil, err + } + + if buf != nil { + return buf.Bytes(), nil + } + return nil, nil +} +``` + +## 3. Cognitive Complexity in `pkg/crypt/crypt.go` + +**Finding:** The `Hash` function in `pkg/crypt/crypt.go` uses a `switch` statement to select the hashing algorithm.

This will make the `Hash` function more extensible and easier to maintain. + +**Refactoring Approach:** + +1. Create a type for the hashing functions. +2. Create a map to store the hashing functions, keyed by the `HashType`. +3. In the `NewService` function, initialize the map with the available hashing algorithms. +4. In the `Hash` function, look up the hashing function in the map and execute it. + +**Proposed Refactoring:** + +```go +// In the Service struct +type hashFunc func(string) string + +type Service struct { + rsa *rsa.Service + pgp *pgp.Service + hashAlgos map[HashType]hashFunc +} + +// In the NewService function +func NewService() *Service { + s := &Service{ + rsa: rsa.NewService(), + pgp: pgp.NewService(), + } + s.hashAlgos = map[HashType]hashFunc{ + LTHN: lthn.Hash, + SHA512: func(p string) string { h := sha512.Sum512([]byte(p)); return hex.EncodeToString(h[:]) }, + SHA256: func(p string) string { h := sha256.Sum256([]byte(p)); return hex.EncodeToString(h[:]) }, + SHA1: func(p string) string { h := sha1.Sum([]byte(p)); return hex.EncodeToString(h[:]) }, + MD5: func(p string) string { h := md5.Sum([]byte(p)); return hex.EncodeToString(h[:]) }, + } + return s +} + +// Refactored Hash function +func (s *Service) Hash(lib HashType, payload string) string { + if f, ok := s.hashAlgos[lib]; ok { + return f(payload) + } + // Default to SHA256 if the algorithm is not found + return s.hashAlgos[SHA256](payload) +} +``` + +## 4. Encapsulation Issues in `pkg/crypt/std/lthn/lthn.go` + +**Finding:** The `lthn` package uses a global `keyMap` variable for character substitutions. This variable can be modified at runtime using the `SetKeyMap` function, creating a package-level state that is shared across all callers. This design has several drawbacks: + +* **Concurrency Unsafe:** If multiple goroutines use the `lthn` package concurrently, a call to `SetKeyMap` in one goroutine will affect the hashing results in all others, leading to race conditions and unpredictable behavior. +* **Difficult to Test:** Tests that need to modify the `keyMap` must use mutexes and cleanup functions to avoid interfering with other tests running in parallel. +* **Poor Encapsulation:** The hashing logic is not self-contained. Its behavior depends on a hidden, global dependency (`keyMap`), which makes the code harder to reason about. + +**Code Exhibiting the Issue:** + +```go +var keyMap = map[rune]rune{ + // ... default mappings +} + +func SetKeyMap(newKeyMap map[rune]rune) { + keyMap = newKeyMap +} + +func Hash(input string) string { + salt := createSalt(input) // Uses the global keyMap + hash := sha256.Sum256([]byte(input + salt)) + return hex.EncodeToString(hash[:]) +} +``` + +**Recommendation:** Refactor the package to be stateless by encapsulating the `keyMap` within a struct. This will make the package safe for concurrent use and easier to test. + +**Refactoring Approach:** + +1. Create a `Lethn` struct to hold the `keyMap`. +2. Create a `New` function to initialize the `Lethn` struct with a default or custom `keyMap`. +3. Change the `Hash`, `Verify`, and `createSalt` functions into methods on the `Lethn` struct. +4. Provide a package-level `Hash` function that uses a default `Lethn` instance for backward compatibility. + +**Proposed Refactoring:** + +```go +package lthn + +import ( + "crypto/sha256" + "encoding/hex" +) + +// Lethn holds the configuration for the LTHN hashing algorithm. +type Lethn struct { + keyMap map[rune]rune +} + +// New creates a new Lethn instance with the provided keyMap. +// If no keyMap is provided, the default keyMap is used. +func New(keyMap ...map[rune]rune) *Lethn { + l := &Lethn{ + keyMap: defaultKeyMap, + } + if len(keyMap) > 0 { + l.keyMap = keyMap[0] + } + return l +} + +var defaultKeyMap = map[rune]rune{ + 'o': '0', 'l': '1', 'e': '3', 'a': '4', 's': 'z', 't': '7', + '0': 'o', '1': 'l', '3': 'e', '4', 'a', '7': 't', +} + +// Hash computes the LTHN hash of the input string. +func (l *Lethn) Hash(input string) string { + salt := l.createSalt(input) + hash := sha256.Sum256([]byte(input + salt)) + return hex.EncodeToString(hash[:]) +} + +// createSalt derives a quasi-salt from the input string. +func (l *Lethn) createSalt(input string) string { + if input == "" { + return "" + } + runes := []rune(input) + salt := make([]rune, len(runes)) + for i := 0; i < len(runes); i++ { + char := runes[len(runes)-1-i] + if replacement, ok := l.keyMap[char]; ok { + salt[i] = replacement + } else { + salt[i] = char + } + } + return string(salt) +} + +// Verify checks if an input string produces the given hash. +func (l *Lethn) Verify(input string, hash string) bool { + return l.Hash(input) == hash +} + +// Default instance for backward compatibility +var defaultLethn = New() + +// Hash is a package-level function that uses the default Lethn instance. +func Hash(input string) string { + return defaultLethn.Hash(input) +} + +// Verify is a package-level function that uses the default Lethn instance. +func Verify(input string, hash string) bool { + return defaultLethn.Verify(input, hash) +} +``` From 5a3a86d07944a6c3d49448566397f81b1a65514a Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Mon, 2 Feb 2026 01:17:02 +0000 Subject: [PATCH 07/15] feat: remediate dependency vulnerabilities - Updated Go version to 1.25.3 in go.mod and go.work to patch standard library vulnerabilities. - Explicitly required github.com/cloudflare/circl v1.6.1 in go.mod to resolve a transitive dependency vulnerability. - Created AUDIT-DEPENDENCIES.md to document the audit findings and remediation steps.

Test Quality + +The overall quality of the tests is high. The project consistently uses the `testify` library for assertions and follows a clear `Good, Bad, Ugly` structure for tests. + +### Test Independence + +- Tests are mostly isolated. However, some tests in `cmd/trix/main_test.go` and `pkg/crypt/crypt_test.go` use global variables, which is an anti-pattern that can lead to test interdependencies. + +### Test Clarity + +- **Descriptive Names:** Most test names are clear and descriptive. Some could be improved, for example, `TestMain_Good` in `cmd/trix/main_test.go` could be renamed to `TestMain_NoArgs_PrintsHelp` to be more specific. +- **Arrange-Act-Assert:** The Arrange-Act-Assert pattern is generally followed, but could be more consistently applied. + +### Test Reliability + +- **Flaky Tests:** No flaky tests were observed during the audit. +- **External Dependencies:** External dependencies are well-mocked, particularly in `pkg/crypt/std/rsa/rsa_test.go` and `pkg/enchantrix/crypto_sigil_test.go`. + +## 3. Missing Tests + +- **Edge Cases:** The tests cover a good range of edge cases, but some are missing, such as the fallback logic in `pkg/trix/trix.go:Unpack`. +- **Error Paths:** The primary gap in testing is the lack of coverage for I/O error paths in `cmd/trix/main.go` and other error paths as detailed in the "Untested Code" section. +- **Integration Tests:** The `TestEncryptedTrixRoundTrip` test in `pkg/trix/crypto_test.go` is a good example of an integration test. More integration tests could be added to cover the interaction between the `trix` CLI and the `pkg` libraries. +- **Performance Tests:** There are no performance tests (e.g., load, stress) in the project. While not critical for a library of this nature, benchmark tests for the cryptographic functions could be beneficial. + +## 4. Anti-Patterns + +- **Shared State:** The use of global variables for the `service` in `pkg/crypt/crypt_test.go` and for `rootCmd`, `exit`, etc. in `cmd/trix/main_test.go` is an anti-pattern. This can lead to test interdependencies and flaky tests. + +## 5. Suggested Tests to Add + +Based on this audit, the following tests should be added to improve coverage and quality: + +1. **`cmd/trix/main_test.go`:** + - Add tests for `handleSigil`, `handleHash`, `handleEncode`, and `handleDecode` that simulate file I/O errors. +2. **`pkg/crypt/crypt_internal_test.go`:** + - Add a test case to cover the `s.pgp != nil` branch of `ensurePGP`. +3. **`pkg/crypt/std/rsa/rsa_internal_test.go`:** + - Add a test case to cover the error path for `x509.MarshalPKIXPublicKey` in `GenerateKeyPair`. +4. **`pkg/enchantrix/crypto_sigil_internal_test.go`:** + - Add a test case to cover the error path in `NewChaChaPolySigilWithObfuscator`. + - Add test cases to cover the error path for `chacha20poly1305.NewX` in `In` and `Out`. +5. **`pkg/enchantrix/sigils_internal_test.go`:** + - Add a test case for `HexSigil.Out` with invalid hex data. + - Add a test case for `Base64Sigil.Out` with invalid base64 data. +6. **`pkg/trix/crypto_internal_test.go`:** + - Add test cases to cover the error paths in `EncryptPayload` and `DecryptPayload`. +7. **`pkg/trix/trix_internal_test.go`:** + - Add a test case for `Unpack` where `OutSigils` is empty. +8. **`examples/examples_test.go`:** + - Add tests for the `main` functions in the `examples` subdirectories.

Go Library API Audit (`pkg/`) + +### 1.1. Overall Design & Consistency + +The public Go API across the `crypt`, `enchantrix`, and `trix` packages is well-designed, consistent, and adheres to Go best practices. The separation of concerns is clear, with each package serving a distinct purpose. + +- **Naming Conventions**: Public functions and types consistently use `PascalCase` as is idiomatic in Go. +- **Error Handling**: Errors are returned as the last value from functions and are descriptive (e.g., `ErrInvalidMagicNumber`, `ErrChecksumMismatch`). +- **Structs vs. Functions**: The API strikes a good balance between service-based structs (`crypt.Service`) and data-centric structs with methods (`trix.Trix`), alongside package-level functions where appropriate (`trix.Encode`, `trix.Decode`). + +### 1.2. Package-Specific Audit + +#### `pkg/crypt` + +- **Strengths**: + - The `crypt.Service` acts as a clean facade for all cryptographic operations. + - Lazy initialization of internal services (`ensureRSA`, `ensurePGP`) is efficient. + - The API is grouped logically: Hashing, Checksums, RSA, and PGP. + - Method names are clear and predictable (e.g., `GenerateRSAKeyPair`, `EncryptRSA`). + +- **Recommendations**: + - **Minor**: The `Hash` function accepts a `crypt.HashType`, while `IsHashAlgo` accepts a `string`. While functional, aligning `IsHashAlgo` to also accept a `crypt.HashType` would improve type safety and consistency. + +#### `pkg/enchantrix` + +- **Strengths**: + - The `Sigil` interface is a powerful and elegant abstraction for data transformation. + - The `NewSigil` factory provides a centralized and user-friendly way to create sigil instances. + - The separation of standard sigils (`sigils.go`) from cryptographic sigils (`crypto_sigil.go`) is logical and improves organization. + - The pre-obfuscation layer is a thoughtful security feature that is well-documented and implemented. + +- **Recommendations**: + - **Feature**: The package does not provide a public function to list all available sigil names. The CLI currently uses a hardcoded list, which could lead to inconsistencies. Exposing a `ListSigils() []string` function from this package would be beneficial. + +#### `pkg/trix` + +- **Strengths**: + - The `.trix` format is clearly defined and implemented. The `Trix` struct serves as a good in-memory representation. + - The `Encode` and `Decode` functions provide a simple, high-level API for serialization. + - Integration with the `enchantrix` package via `Pack` and `Unpack` methods is seamless. + - Constants are used effectively for header keys (e.g., `HeaderKeyEncrypted`), preventing magic strings. + +- **Recommendations**: + - None. The API is robust and well-designed. + +## 2. CLI API Audit (`cmd/trix/`) + +### 2.1. Overall Design & Consistency + +The `trix` CLI is built on `spf13/cobra`, a standard for modern Go CLIs. It follows common Unix conventions, including the use of `stdin`/`stdout` and file-based I/O. + +- **Command Structure**: The command hierarchy is logical and easy to navigate (`trix encode`, `trix decode`, `trix hash`). +- **Flags**: Flags are consistent across commands (`--input`, `--output`, `--magic`) and include convenient short aliases (`-i`, `-o`, `-m`). +- **User Interaction**: The tool provides clear error messages and behaves predictably. + +### 2.2. Specific Commands Audit + +- **`trix encode`/`decode`**: + - These commands are the core of the tool and function as expected. + - **Minor Recommendation**: Sigils are passed as positional arguments (e.g., `trix encode base64 gzip`). While this works, a dedicated flag like `--sigils "base64,gzip"` or repeated flags (`--sigil base64 --sigil gzip`) would be more self-documenting and in line with typical `cobra` application design. + +- **`trix hash`**: + - The command is straightforward and works as expected. + +- **Direct Sigil Commands** (`trix hex`, `trix base64`, etc.): + - This is a clever and useful feature that exposes the power of the `enchantrix` library directly from the command line for quick, one-off transformations. + +### 2.3. Maintainability + +- **Recommendation**: As noted in the `enchantrix` section, the `availableSigils` slice in `cmd/trix/main.go` is hardcoded. This creates a maintenance burden, as any new sigil added to the `enchantrix` package must also be manually added to this list. This could be resolved by having the `enchantrix` package expose a function to list available sigils. + +## 3. Conclusion + +The Enchantrix project exhibits a high degree of API quality and consistency in both its Go library and its command-line interface. The design is thoughtful, robust, and adheres to idiomatic Go practices. The few recommendations provided are minor and aimed at further improving maintainability and user experience rather than fixing significant flaws.

It is protocol-agnostic, meaning it can be used to store any type of data. Its primary purpose is to provide a flexible and extensible format for data that may need to be transformed or encrypted. + +### What are Sigils? + +Sigils are the core concept of the Enchantrix transformation framework. Each Sigil represents a single, reversible data transformation, such as encoding, compression, or hashing. They can be chained together to create powerful and flexible transformation pipelines. + +## Development + +### How do I add a new Sigil? + +To add a new Sigil, you need to create a new struct that implements the `enchantrix.Sigil` interface. This involves implementing the `In()` and `Out()` methods. Once your Sigil is implemented, you can add it to the `enchantrix.NewSigil()` factory function. + +### Can I use my own magic number for the .trix format? + +Yes, the `trix.Encode()` and `trix.Decode()` functions accept a custom 4-byte magic number string.

The non-thread-safe `if s.service == nil` check could lead to multiple initializations when accessed concurrently. This commit resolves the race condition by using `sync.Once` to ensure that the initialization for each service is performed exactly once, making the `Service` struct safe for concurrent use. Additionally, a new test file, `race_test.go`, has been added to provide a regression test for this specific scenario. A new file, `AUDIT-CONCURRENCY.md`, has been created to document the findings of the concurrency audit, the remediation steps taken, and the verification process.

Executive Summary + +A concurrency audit was performed on the codebase to identify potential race conditions and thread-safety issues. The audit focused on encryption operations, connection pooling, cache synchronization, and key management. + +A critical data race was identified in the lazy initialization of the RSA and PGP services within the `pkg/crypt` package. This could lead to unpredictable behavior and resource leaks under concurrent use. + +The issue was resolved by implementing thread-safe initialization using the `sync.Once` primitive from the Go standard library. + +## 2. Methodology + +The audit consisted of the following steps: + +1. **Static Analysis:** A manual review of the codebase was conducted, focusing on areas with high potential for concurrency issues, such as the `pkg/crypt` package. +2. **Dynamic Analysis:** The Go race detector (`go test -race ./...`) was used to identify data races during test execution. A new test case was created to specifically trigger the suspected race condition. + +## 3. Findings + +### 3.1. Data Race in Lazy Initialization + +- **Location:** `pkg/crypt/crypt.go`, in the `ensureRSA()` and `ensurePGP()` methods. +- **Description:** The `ensureRSA()` and `ensurePGP()` methods used a non-thread-safe `if s.rsa == nil` check for lazy initialization. This created a race condition where multiple goroutines could enter the initialization block simultaneously, leading to multiple service instantiations and overwriting the service pointer. +- **Impact:** This could cause unpredictable behavior, memory leaks, and potentially panics if the service initialization had side effects. +- **Reproduction:** The race condition was reliably reproduced by creating a new test case (`pkg/crypt/race_test.go`) that called the `ensure` methods from multiple goroutines in parallel. + +## 4. Remediation + +The data race was remediated by using `sync.Once` to ensure that the initialization of the `rsa.Service` and `pgp.Service` happens exactly once, even when called from multiple goroutines. + +The following changes were made to `pkg/crypt/crypt.go`: + +1. Added `rsaOnce sync.Once` and `pgpOnce sync.Once` fields to the `Service` struct. +2. Modified `ensureRSA()` to use `s.rsaOnce.Do()`. +3. Modified `ensurePGP()` to use `s.pgpOnce.Do()`. + +## 5. Verification + +The fix was verified by running the test suite with the race detector (`go test -race ./...`). The tests passed without any race warnings, confirming that the fix is effective. The new test case in `pkg/crypt/race_test.go` now serves as a regression test for this specific issue. + +## 6. Conclusion + +The audit identified and remediated a critical data race in the `pkg/crypt` package. The codebase is now more robust and safe for concurrent use.

The output is easy to read and understand. + +### Build System +- Intuitive commands? + - Yes, the `Taskfile.yml` provides a clear and intuitive set of commands (`test`, `build`, `fmt`, `vet`). The standard `go` commands also work as expected. +- Clear error messages? + - Yes, the build system's error messages (from `go build`, `go test`, etc.) are standard and clear to Go developers. +- Incremental builds? + - Yes, Go's build system provides incremental builds by default. + +### Tooling +- IDE Support - Editor configs? + - There are no editor-specific configurations (e.g., `.vscode/`, `.editorconfig`) in the repository. Adding an `.editorconfig` file would be a good practice to ensure consistent formatting across different editors. +- Linting - Auto-fixable? + - The `task vet` command runs `go vet`, which is a standard linter for Go. It does not provide auto-fixing. More advanced linters like `golangci-lint` could be added for more comprehensive checks and auto-fixing capabilities. +- Formatting - Pre-commit hooks? + - The `task fmt` command runs `go fmt`. There are no pre-commit hooks configured to automatically format code before committing.

For example, providing an invalid hash algorithm to the `hash` command produces the following output: + +``` +Error: invalid hash algorithm: invalid-algorithm +Usage: + trix hash [algorithm] [flags] + +Flags: + -h, --help help for hash + -i, --input string Input file (or stdin) +``` + +This is a good error message because it: +1. Clearly states what is wrong ("invalid hash algorithm"). +2. Shows the invalid value that was provided ("invalid-algorithm"). +3. Prints the usage information for the command, which helps the user correct the input. + +### Progress Feedback +- Long operations? + + - The tool is designed for local data transformation and is very fast. There are no long-running operations that would require progress feedback. + +### Configuration +- Sensible defaults? + + - The CLI has sensible defaults. For example, the `input` and `output` flags default to stdin and stdout, respectively, which is a common and useful convention for CLI tools. + +## Pain Points +- **Undocumented Dependencies:** The `task` dependency and the `GOTOOLCHAIN` fix for Go 1.25 are not documented, which could cause minor frustration for new contributors. +- **CLI Usability:** The large number of sigil commands in the root help output can be overwhelming, and the `encode`/`decode` help texts are missing information about sigils. +- **Lack of Automated Tooling:** The absence of pre-commit hooks for formatting and more advanced linting means that maintaining code quality relies more on manual developer effort. + +## Suggestions for Improvement + +1. **Documentation:** + - Add a "Development" or "Contributing" section to the `README.md` that explicitly lists all development dependencies (`task`, `mkdocs`). + - Add a note about the `GOTOOLCHAIN` fix for Go 1.25 to the "Development" section. + +2. **CLI:** + - Consider grouping the sigil commands under a single `sigil` subcommand (e.g., `trix sigil base64`) to declutter the root command's help output. + - Add `[sigils...]` to the `Usage` string for the `encode` and `decode` subcommands to make it clear that they accept sigils as positional arguments. + +3. **Tooling:** + - Add an `.editorconfig` file to ensure consistent formatting across different editors. + - Add a pre-commit hook (e.g., using Husky or a similar tool) to automatically run `go fmt` before each commit. + - Consider adding a more advanced linter like `golangci-lint` to the `Taskfile.yml` and the pre-commit hooks to catch a wider range of issues automatically.
