Diehard is a battery of tests developed by Goerge Marsaglia to test for statistical randomness. Originally written in fortran, a C version was created using the f2c program. DiehardC is a C version of Diehard developed by Scott Nelson with readability and portability in mind. The test included in Diehard are: the Birthday Spacing Test, the Overlapping 5-Permutation Test, the Binary Rank Test, the Bitstream Test, the OPSO, OQSO and DNA Tests, the Count-The-1's Test, the Parking Lot Test, the Minimum Distance Test, the 3D Spheres Test, the Squeeze Test, The Overlapping Sums Test, the Runs Test, and the Craps Test.

Ent applies various tests to sequences of bytes stored in files and reports the results of those tests. The program is useful for those evaluating pseudorandom number generators for encryption and statistical sampling applications, compression algorithms, and other applications where the information density of a file is of interest. Ent performs the following tests: Entropy, Chi-Square, Arithmetic Mean, Monte Carlo Value for Pi and Serial Correlation Coefficient .

Random Number Generator is a Windows95 based application designed to generate random numbers of any length. Random Number Generator v.1.1 allow users to do choice random number generator, which built into this application.This is linear congruential and bit shift random number generators.This feature is used to generate an extremely random seed value. Random number generators written in low-level language, and some of random number generators, which built into this application, is impossible to write in high-level language (Basic,Pascal,C++ and other). Random Number Generator will generate to 200 numbers.

The sigs package provides secure digital signatures with verification at secret-key speeds. 2048-bit verification on a Pentium-100 takes under 150 microseconds; for comparison, encrypting 2048 bits with the fastest available DES implementation takes 113 microseconds.
