API Reference

// Generate HMAC digest
public func generate(
    key : [Nat8],              // Key for HMAC
    msg : Iter.Iter<Nat8>,     // Message to hash
    algorithm : HashAlgorithm, // Hash algorithm to use
) : Blob                       // Returns HMAC digest as Blob

// Define available hash algorithms
public type HashAlgorithm = {
    #sha256;                                  // Standard SHA-256
    #custom : (Iter.Iter<Nat8>) -> Blob;      // Custom hash function
};
