                                 byte[] secret)
        Decrypts a message using the supplied secretKey and nonce Returns an decrypted message, using the `secret` and `nonce`. **example** ```java naclDecrypt([...], [...], [...]); // => [...] ```

      • naclEncrypt

        public static Nacl.Encrypted naclEncrypt​(byte[] message,
                                         byte[] secret)
        Encrypts a message using the supplied secretKey and nonce Returns an encrypted message, using the `secretKey` and `nonce`. If the `nonce` was not supplied, a random value is generated. **example** ```java naclEncrypt([...], [...]); // => [...] ```

      • naclEncrypt

        public static Nacl.Encrypted naclEncrypt​(byte[] message,
                                         byte[] secret,

      • naclKeypairFromSeed

        public static Types.Keypair naclKeypairFromSeed​(byte[] seed)
        Creates a new public/secret keypair from a seed. Returns a object containing a `publicKey` & `secretKey` generated from the supplied seed. **example** ```java naclKeypairFromSeed(...); // => { secretKey: [...], publicKey: [...] } ```

      • naclSign

        public static byte[] naclSign​(byte[] message,
                              Types.Keypair keypair)
        Signs a message using the supplied secretKey Returns message signature of `message`, using the `secretKey`. **example** ```java naclSign([...], [...]); // => [...] ```

      • naclVerify

        public static boolean naclVerify​(byte[] message,
                                 byte[] signature,
                                 byte[] publicKey)
        Verifies the signature on the supplied message. Verifies the `signature` on `message` with the supplied `plublicKey`. Returns `true` on sucess, `false` otherwise. **example** ```java naclVerify([...], [...], [...]); // => true/false ```
