DES ENCRYPTION/DECRYPTION PACKAGE V1.0 A DES package is available through anonymous ftp on the host <chalmers.se>: chalmers.se:~ftp/pub/des/ -rw-r--r-- 1 root wheel 836 Oct 23 15:20 COPYRIGHT.1.0 -rw-r--r-- 1 root wheel 3675 Oct 23 15:53 README.1.0 -rw-r--r-- 1 root wheel 5413 Oct 23 17:31 des.1.0.list -rw-r--r-- 1 root staff 89355 Oct 23 16:04 des.1.0.tar.Z The package contains: * A DES library with functions conforming to the functions described in the DES_CRYPT(3) manual page from MIT. * Additional library functions not in the MIT library. * File encryption/decryption program and random key generation program. The additional functions includes handling of encrypted data and keys as pure text (64-bit hexadecimal numbers), key schedule test (weak keys, semi-weak keys, ...). The encryption/decryption program supports multiple encryption modes (electronic code book, cipher block chaining, modified cipher block chaining, 8-bit cipher feedback and 8-bit output feedback) and checksum calculation. Encrypted data can be represented as ordinary text (64-bit hexadecimal numbers). Fetch the file README.1.0 for more information. If you find any bugs or porting problems, please send fixes or a description of the problem. _ Stig Ostholm Chalmers University of Technology Department of Computer Engineering ---------------------------------- <ostholm@ce.chalmers.se>
