Method Detail

cryptoGenericHashKeygen

Key cryptoGenericHashKeygen()

Generate a hashing key.

Returns:

A hashing key.

cryptoGenericHashKeygen

Key cryptoGenericHashKeygen(int size)
                     throws SodiumException

Generate a hashing key with a size.

Parameters:

size - The size of the hashing key between GenericHash.KEYBYTES and GenericHash.KEYBYTES_MAX.

Returns:

A hashing key.

Throws:

SodiumException

cryptoGenericHash

java.lang.String cryptoGenericHash(java.lang.String in)
                            throws SodiumException

Hash a string without a key.

Parameters:

in - The string to hash.

Returns:

The hashed string.

Throws:

SodiumException

cryptoGenericHash

java.lang.String cryptoGenericHash(java.lang.String in,
                                   Key key)
                            throws SodiumException

Hash a string with a key, so later on you can verify the hashed string with the key. If you're hashing a password please see PwHash.Lazy.cryptoPwHashStr(String, long, NativeLong)} instead.

Parameters:

in - The string to hash.

key - Can be null.

Returns:

A hashed string.

Throws:

SodiumException

cryptoGenericHashInit

boolean cryptoGenericHashInit(byte[] state,
                              Key key,
                              int outLen)

Initialise a multi-part hashing operation.

Parameters:

state - The state which holds the key and operation.

key - The key as generated by cryptoGenericHashKeygen().

outLen - The size of the final hash.

Returns:

True if initialised.

cryptoGenericHashUpdate

boolean cryptoGenericHashUpdate(byte[] state,
                                java.lang.String in)
                         throws SodiumException

Hash a part of a multi-part hash.

Parameters:

state - State as put into cryptoGenericHashInit(byte[], Key, int).

in - A part of a string to hash.

Returns:

True if hashed successfully.

Throws:

SodiumException

cryptoGenericHashFinal

java.lang.String cryptoGenericHashFinal(byte[] state,
                                        int outLen)
                                 throws SodiumException

Finalise the hashing operation.

Parameters:

state - State as put into cryptoGenericHashInit(byte[], Key, int).

outLen - The size of the final hash.

Returns:

The final hash.

Throws:

SodiumException
