Cryptography Functions

The Crypto category provides cryptographic operations that mirror the functionality of Crypto nodes.

Available Functions​

  • Crypto.generateRandom(length, algorithm) - Generates random bytes
  • Crypto.hash(value, algorithm, binaryPropertyName) - Computes a hash of the input value
  • Crypto.hmac(value, key, algorithm, binaryPropertyName) - Computes HMAC (Hash-based Message Authentication Code)
  • Crypto.sign(value, privateKey, algorithm, binaryPropertyName) - Signs data with a private key

Examples​

Generating Random Data​

local random = Crypto.generateRandom(32, "SHA256")

Hashing​

local hash = Crypto.hash("Hello World", "SHA256")
-- Returns hexadecimal hash string

HMAC​

local hmac = Crypto.hmac("message", "secret-key", "SHA256")
-- Returns HMAC value

Signing​

local signature = Crypto.sign("data", "private-key", "SHA256")
-- Returns signature

Parameters​

  • value - The input value to hash/sign
  • key - The secret key for HMAC
  • privateKey - The private key for signing
  • algorithm - Hash algorithm (e.g., "SHA256", "SHA512", "MD5")
  • binaryPropertyName - Optional property name for binary data
  • length - Length of random data to generate

Return Values​

All functions return string values (hexadecimal representation for hashes and signatures).
