This function is provided by the bundled argon2 extension and also by the crypto extension (which replaces it). For new code, prefer Argon2Verify() for consistent naming with BCryptVerify() and SCryptVerify().

    secret = createUUID();
    dump(var=secret, label="input string");
    hashed = generateArgon2Hash(secret);
    dump(var=hashed, label="generateArgon2Hash");
    decoded= argon2checkhash(secret, hashed);
    dump(var=decoded, label="argon2checkhash matches");
