- DES ENCRYPTION/DECRYPTION PACKAGE V1.0
-
-
- A DES package is available through anonymous ftp on the host <chalmers.se>:

- -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.
