aptimelib is a new, extremely portable, generic, 64-bit, time/date library. It implements the proposal by David R. Tribble ( http://david.tribble.com/text/c0xlongtime.html ), featuring epoch basis, microsecond granularity, and platform translation.
Portable, optimised implementation of Bruce Schneier's 64-bit symmetric block cipher, Blowfish. Includes support for ECB, CBC, CFB, OFB and CTR block cipher modes, weak key detection and parallelisation using OpenMP.
