10-33: LGTM: Test function for RIPEMD-160 implemented with suggestions.The test function
ripemd160_testis well-structured and covers basic cases. However, consider the following improvements:
- Use a more specific error code or message in the assertion for better debugging.
- Add more test cases, including longer inputs, to ensure thorough testing.
- Consider parameterizing the test function to allow for easier addition of test cases.
Here's a suggested improvement for the assertion:
- assert!(hash_expected == hash, 1); + assert!(hash_expected == hash, 0x1000); // RIPEMD-160 hash mismatchWould you like assistance in implementing these suggestions?
8-33: Summary: RIPEMD-160 hash function and test successfully implemented.The additions to the
std::hashmodule are well-implemented and align with the existing structure. The newripemd160function expands the module's capabilities, and the corresponding test function ensures its correctness.Consider the following for future improvements:
- Expand test cases to cover a wider range of inputs.
- Implement property-based testing for more thorough validation.
- Add documentation comments for the new function to maintain consistency with other module functions.
Overall, these changes enhance the functionality of the hash module without introducing any apparent issues.

76-105: LGTM! Consider a minor improvement for consistency.The
native_ripemd160function is well-implemented and follows the structure of existing hash functions. It correctly handles gas costs, input validation, and hash computation using theripemdcrate.For consistency with the
sha2_256andsha3_256functions, consider using theDigesttrait method directly:- let mut hasher = ripemd::Ripemd160::new(); - hasher.update(&hash_arg); - let hash_vec = hasher.finalize().to_vec(); + let hash_vec = ripemd::Ripemd160::digest(hash_arg.as_slice()).to_vec();This change would make the implementation more concise and align it with the other hash functions in this file.

76-116: Summary: RIPEMD-160 hash function successfully implementedThe changes in this file successfully introduce the RIPEMD-160 hash function to the Move standard library. The implementation follows the established patterns for hash functions in this module, including proper gas cost calculation and error handling. The
make_allfunction is correctly updated to expose the new native function.These changes enhance the cryptographic capabilities of the Move language, allowing developers to use RIPEMD-160 in their smart contracts. This addition is particularly useful for applications that require compatibility with systems or protocols that use RIPEMD-160, such as certain blockchain address derivation schemes.
Consider documenting the use cases for RIPEMD-160 in the Move ecosystem, particularly in comparison to the existing SHA-2 and SHA-3 functions, to guide developers in choosing the appropriate hash function for their needs.

42-45: LGTM! Consider adding a brief comment for clarity.The new gas parameters for Bech32 encoding and decoding are consistent with existing patterns and values in the file. The base and per-byte costs are appropriate and align well with similar operations like base64 encoding/decoding.
Consider adding a brief comment above these new parameters to explain their purpose and relation to blockchain address handling. This would improve code documentation and maintainability.

7-10: Review the usage of#[test_only]withusestatementsThe
#[test_only]attribute is applied to theusestatements forminitia_std::stringandminitia_std::hex. Ensure that this attribute correctly limits the scope of these imports to test code. Alternatively, consider moving these imports inside the test functions to clearly indicate they are used only in tests.
31-32: Avoid variable shadowing fordataintest_decodeIn the
test_decodefunction, the variabledatais reassigned after encoding it to a hex string (lines 31 and 37). This shadows the originaldatavariable obtained from thedecodefunction, which can lead to confusion. Consider using a different variable name, such ashex_data, to improve code readability.Also applies to: 37-38

28-33: Implementto_wordsandfrom_wordsfunctionsThe comments mention
native public fun to_wordsandfrom_words, but these functions are not implemented in the code. If these functions are intended to be part of the module, please provide their implementations to ensure full functionality.Would you like assistance in implementing these functions?

8-8: LGTM: New RIPEMD-160 hash function added.The new native function
ripemd160is a good addition to the hash module. Its signature is consistent with other hash functions, and the native declaration is appropriate for cryptographic implementations.crates/natives/Cargo.toml (1)
28-28: New dependency added: Verify necessity and usageThe addition of the
ripemddependency aligns with the PR objectives related to implementing RIPEMD-160 hashing. This is a commonly used cryptographic hash function, often used in blockchain applications.A few points to consider:
- Ensure that RIPEMD-160 is indeed required for your project's cryptographic needs.
- Verify that the
ripemdcrate is actively maintained and has no known security vulnerabilities.- Confirm that the workspace-level version specification (
workspace = true) is intentional and consistent with other dependencies.To ensure the

19-20: Verify gas cost values for RIPEMD-160.The addition of gas parameters for RIPEMD-160 is appropriate and consistent with other hash functions. However, the values are identical to SHA2-256, which may not accurately reflect the computational cost of RIPEMD-160.
Please confirm:
- Are these values based on benchmarks specific to RIPEMD-160, or are they initial estimates?
- If they are estimates, consider running separate benchmarks for RIPEMD-160 to ensure accurate gas costs.
To assist in verifying the relative performance of RIPEMD-160 compared to SHA2-256, you could run the following benchmark:
