Java Console Applications

ARCFourGen - a pseudo-random sequence generator that uses the algorithm alleged to be the RC4^® cipher developed by Ron Rivest.

ISAACGen - generates a sequence of pseudo-random bytes using Bob Jenkins' ISAAC cryptographic random number generator.

SOBER128Gen - uses the stream cipher designed by Greg Rose and Phil Hawkes at Qualcomm to generate a sequence of pseudo-random bytes.

jEnt - applies statistical tests to sequences of bytes to assist in the evaluation of pseudo-random sequence generators. jEnt is a translation of ent which was originally developed in C by John Walker.

Java GUI Applications

GUIjEnt - a GUI front-end for jEnt.

SeedGen - generates printable character sequences that may be useful for seeding pseudo-random number generators or for non-obvious passwords.

RanFile - creates files filled with bytes whose contents are pseudo-random values.
