Method Details

cryptoSecretBoxKeygen

Key cryptoSecretBoxKeygen()

Generates a secret symmetric key.

Returns:

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

cryptoSecretBoxEasy

String cryptoSecretBoxEasy(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

String cryptoSecretBoxOpenEasy(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(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).

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

cryptoSecretBoxOpenDetached

String cryptoSecretBoxOpenDetached(DetachedEncrypt cipherAndMac,
 byte[] nonce,
 Key key)
                            throws SodiumException

Decrypts a message.

Parameters:

cipherAndMac - 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
