CryptoRSA Methods

RSA

Methods to encrypt / decrypt / sign / verify data with RSA style encryption.

CryptoRSA.createSignature

Creates a RSA signature Base64 encoded.

Signature

String CryptoRSA.createSignature(String key, String dataB64)

Parameters

Name	Type	Description
key	String	PEM encoded Private Key
dataB64	String	Base64 encoded message to sign

CryptoRSA.decrypt

Asymmetric RSA decryption. Result is Base64 encoded to support binary data. If you are expecting clear text from the decryption, use CryptoEncoding.base64Decode on the result.

Signature

String CryptoRSA.decrypt(String key, String encryptedB64)

Parameters

Name	Type	Description
key	String	PEM encoded Private Key
encryptedB64	String	Base64 encoded encrypted data

CryptoRSA.encrypt

Asymmetric RSA encryption. Result is Base64 encoded.

Signature

String CryptoRSA.encrypt(String key, String dataB64)

Parameters

Name	Type	Description
key	String	PEM encoded Public or Private Key
dataB64	String	Base64 encoded data. Supports binary data.

CryptoRSA.verifySignature

Verifies a RSA signature. Returns true on successful validation.

Signature

boolean CryptoRSA.verifySignature(String key, String dataB64, String signatureB64)

Parameters

Name	Type	Description
key	String	PEM encoded Public or Private Key
dataB64	String	Base64 encoded message that was signed
signatureB64	String	Base64 encoded RSA signature to verify
