Returns:

Returns the derived key a byte array

Throws:

WSSecurityException

generateSalt

public static byte[] generateSalt(boolean useForMac)

This static method generates a 128 bit salt value as defined in WSS Username Token Profile.

Parameters:

useForMac - If true define the Salt for use in a MAC

Returns:
