Method Detail

cryptoSecretBoxKeygen

Key cryptoSecretBoxKeygen()

Generates a secret symmetric key.

Returns:

A secret symmetric key which has been through Helpers.Lazy.sodiumBin2Hex(byte[]).

cryptoSecretBoxEasy

java.lang.String cryptoSecretBoxEasy(java.lang.String message,
                                     byte[] nonce,
                                     Key key)
                              throws SodiumException

Encrypts a message.

Parameters:

message - The message to encrypt.

nonce - A randomly generated nonce of size SecretBox.NONCEBYTES. Use Random.randomBytesBuf(int).

key - The key. A hexadecimal string that's been through Helpers.Lazy.sodiumBin2Hex(byte[]).

Returns:

The cipher byte array that's been Helpers.Lazy.sodiumBin2Hex(byte[])'ified.

Throws:

SodiumException

cryptoSecretBoxOpenEasy

java.lang.String cryptoSecretBoxOpenEasy(java.lang.String cipher,
                                         byte[] nonce,
                                         Key key)
                                  throws SodiumException

Decrypts a message.

Parameters:

cipher - The hexadecimal cipher text. See Helpers.Lazy.sodiumBin2Hex(byte[]).

nonce - The nonce that was used when you encrypted with cryptoSecretBoxEasy(String, byte[], Key).

key - The key. A hexadecimal string that's been through Helpers.Lazy.sodiumBin2Hex(byte[]).

Returns:

The decrypted message.

Throws:

SodiumException

cryptoSecretBoxDetached

DetachedEncrypt cryptoSecretBoxDetached(java.lang.String message,
                                        byte[] nonce,
                                        Key key)
                                 throws SodiumException

Encrypts a message with the mac separately

Parameters:

message - The message to encrypt.

nonce - A randomly generated nonce of size SecretBox.NONCEBYTES. Use Random.randomBytesBuf(int).
