                              byte[] S,
                              int N,

                              int dkLen)

Generate a key using the scrypt key derivation function.

Parameters:

P - the bytes of the pass phrase.

S - the salt to use for this invocation.

N - CPU/Memory cost parameter. Must be larger than 1, a power of 2 and less than 2^(128 * r / 8).

r - the block size, must be >= 1.

p - Parallelization parameter. Must be a positive integer less than or equal to Integer.MAX_VALUE / (128 * r * 8).

dkLen - the length of the key to generate.

Returns:

the generated key.
