Method Detail

getAlgorithm

String getAlgorithm()

Gets the algorithm name.

Returns:

Algorithm name.

setRandomProvider

void setRandomProvider(SecureRandom random)

Sets the source of random data for cryptographic operations needing a random data source, such as generating a random salt value.

Parameters:

random - Provider of cryptographically strong random data.

getRandomData

byte[] getRandomData(int nBytes)

Gets random bytes from the random provider of this instance in the amount specified.

Parameters:

nBytes - Number of bytes of random data to retrieve.

Returns:

Byte array of random data.
