Crypto Class
The Crypto class provides AES-256-GCM encryption and HMAC-SHA256.
crypto = new Cryptocrypto.aesEncrypt(cPlaintext, cKey)
Encrypt plaintext using AES-256-GCM. Returns base64-encoded ciphertext with IV and tag.
encrypted = crypto.aesEncrypt("secret data", "0123456789abcdef0123456789abcdef")crypto.aesDecrypt(cCiphertext, cKey)
Decrypt AES-256-GCM ciphertext. Returns decrypted plaintext.
decrypted = crypto.aesDecrypt(encrypted, "0123456789abcdef0123456789abcdef")crypto.hmacSha256(cMessage, cKey)
Compute HMAC-SHA256 signature. Returns hex-encoded signature.
sig = crypto.hmacSha256("message", "secret-key")crypto.hmacVerify(cMessage, cKey, cSignature)
Verify an HMAC-SHA256 signature. Returns 1 if valid, 0 otherwise.
if crypto.hmacVerify("message", "secret-key", sig)
# Signature valid
ok
