Random-number generator test library


libdieharder is the core library of dieharder and friends, designed to be "the last suite of random number testers you'll ever wear". It can test any of its many prebuilt and library linked generators (basically all of those in the GNU Scientific Library plus a number of others from various sources) or a potentially random dataset in either an ascii-formatted or raw (presumed 32 bit uint) binary file. It is fairly straightforward to wrap new software generators for testing, or to add hardware generators that have a software interface for testing, and the file input method permits pretty much any software or hardware RNG to be tested using libdieharder calls.

libdieharder has as a design goal the full encapsulation in an extensible shell of basically all the random number tests I have been able to find -- George Marsaglia's "diehard" battery of tests, STS (v1.6) from NIST FIPS, Knuth's tests, and more. Check in the man page(s) or /usr/share/dieharder*/dieharder.pdf for documentation.

This package provides the shared library.
