initialize

public void initialize(DHParams params,
                       RandomBitsSource rbs)

Initializes the key pair generator with the given parameters and source of randomness.

Parameters:

params - The DHParams object to be used to generate key pair.

rbs - A secure random bits source.

initialize

public void initialize(int L,
                       int m,
                       RandomBitsSource rbs)

Initializes the key pair generator with the given source of randomness. New domain parameters of the specified size are generated.

Parameters:

L - The size in bits for p.
