                           throws java.security.InvalidParameterException

Allow a value to be passed in for what is normally supposed to be random data. This is primarily useful to validate a known-answer test. The string param needs to be "k", and the object value needs to be either null (which says fall back to using random values) or a string with the decimal value for k.

Throws:

java.security.InvalidParameterException
