# status finished. passes tests. # intro this is a DES library. it is written in portable c, it does not need to know if it runs on a little or big endian machine. it is easy to understand as it directly uses the tables from the DES specification (only the sboxes have a different layout, generated by the included sbox.py). it is not optimized. it does have tests, which it passes. the code is in the public domain for easy inclusion in external software. # install this is just a library. "make" will compile it (libdes.a). "make run" will run the test suite. # latest version get it from http://www.ueber.net/code/r/des # licence & author all files are in the public domain. this code has been written by mechiel lukkien, reachable at firstname.lastname@example.org or email@example.com. # caveats des.h uses the types "uchar" and "uvlong". if your system does not define those, you can define them yourself (before inclusion of des.h). for example: typedef unsigned char uchar; typedef unsigned long long uvlong; #include "des.h"
