public abstract class FIPS186Random extends SecRandom
This pseudo random works according to FIPS PUB 186-2 with an hash
function as one-way function
G(t,c). As this is a
general purpose random generator, the
operation is omitted. As a consequence of omitting this modulo
operation, the changes to the FIPS PUB 186-2 pseudo random generator
need not be considered, because they have no influence in this case.
The concrete classes are derived from this class and provide a raw hash algorithm. The raw hash provides access to the raw compression function. This algorithm requires a raw hash rather than a complete hash, because this FIPS algorithm operates on the compression function part and not on the complete hash function. The complete hash function includes a certain padding, which this algorithm does not; it simply appends zeros up to the required block size.
