Method Detail

naclDecrypt

public static byte[] naclDecrypt(byte[] encrypted,
                                 byte[] nonce,
                                 byte[] secret)

Decrypts a message using the supplied secretKey and nonce Returns an decrypted message, using the secret and nonce. example

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

naclEncrypt([...], [...]); // => [...]

naclEncrypt

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

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

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

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

naclVerify([...], [...], [...]); // => true/false
