\section{DES functions}
The DES functions conform to the encryption interface required by the
Kerberos version 5 library, and provide an encryption mechanism based on
the DES Cipher-block chaining mode (CBC), with the addition of a
cyclical redundancy check (CRC-32) for integrity checking upon
decryption.

The functions have the same signatures as those described by the main
library document; the names are:
{\obeylines
\funcname{mit_des_encrypt_func}
\funcname{mit_des_decrypt_func}
\funcname{mit_des_process_key}
\funcname{mit_des_finish_key}
\funcname{mit_des_string_to_key}
\funcname{mit_des_init_random_key}
\funcname{mit_des_finish_random_key}
\funcname{mit_des_random_key}
}
The \datatype{krb5_cryptosystem_entry} for this cryptosystem is
\globalname{mit_des_cryptosystem_entry}.
