MCJS - Milagro Crypto JavaScript
MCJS is a standards compliant JavaScript cryptographic library with no external dependencies except for the random seed source.
MCJS supports the standards for RSA, ECDH, ECIES, ECDSA and M-PIN, AES-GCM encryption/decryption, SHA256, SHA384, SHA512 and SHA3 hash functions and a cryptographically secure random number generator. Furthermore we recently added New Hope, a post-quantum key exchange.
MCJS is Node.js compatible and browser compatible (see some examples below).
