Method Detail

init

void init(KeyGenerationParameters params)

Initialise this SecretKeyGenerator. Implementations should be able to initialise with defaults, if no parameters are given (i.e. params being null). Usually, defaults mean to generate 256 bit keys.

Parameters:

params - the parameters or null, if defaults should be used.

generateKey

KeyParameter generateKey()

Generate random a secret key. Throws an IllegalStateException, if init(KeyGenerationParameters) was not yet called.

Returns:

the newly created secret key; never null.
