Module crypto

ballerina/crypto Ballerina library

2.7.2

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, and ML-DSA-65 post-quantum signature algorithm as well.

Key Derivation Functions (KDF)

The crypto module supports HMAC-based Key Derivation Function (HKDF). HKDF is a key derivation function that uses a Hash-based Message Authentication Code (HMAC) to derive keys.

Key Exchange Mechanisms (KEM)

The crypto module supports Key Exchange Mechanisms (KEM). It includes RSA-KEM and post-quantum ML-KEM-768 for both encapsulation and decapsulation.

Hybrid Public Key Encryption (HPKE)

The crypto module supports Hybrid Public Key Encryption (HPKE). It supports post-quantum ML-KEM-768-HPKE and RSA-KEM-ML-KEM-768-HPKE for encryption and decryption.
