API
Declarations
ballerina/crypto Ballerina library
Overview
This module provides common cryptographic mechanisms based on different algorithms.
The Ballerina crypto
module facilitates APIs to do operations like hashing, HMAC generation, checksum generation, encryption, decryption, signing data digitally, verifying digitally signed data, etc., with different cryptographic algorithms.
Hashes
The crypto
module supports generating hashes with 5 different hash algorithms MD5, SHA1, SHA256, SHA384, and SHA512. Also, it supports generating the CRC32B checksum.
HMAC
The crypto
module supports generating HMAC with 5 different hash algorithms: MD5, SHA1, SHA256, SHA384, and SHA512.
Decode private/public key
The crypto
module supports decoding the RSA private key from a .p12
file and a key file in the PEM
format. Also, it supports decoding a public key from a .p12
file and a certificate file in the X509
format. Additionally, this supports building an RSA public key with the modulus and exponent parameters.
Encrypt and decrypt
The crypto
module supports both symmetric key encryption/decryption and asymmetric key encryption/decryption. The RSA algorithm can be used for asymmetric-key encryption/decryption with the use of private and public keys. The AES algorithm can be used for symmetric-key encryption/decryption with the use of a shared key.
Sign and verify
The crypto
module supports signing data using the RSA private key and verification of the signature using the RSA public key. This supports MD5, SHA1, SHA256, SHA384, and SHA512 digesting algorithms as well.
