public static byte[] generate(byte[] P,
                              byte[] S,
                              int N,
                              int r,

                              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.
