\brief DES-CBC buffer encryption/decryption

\note Upon exit, the content of the IV is updated so that you can call the function same function again on the following block(s) of data and get the same result as if it was encrypted in one call. This allows a “streaming” usage. If on the other hand you need to retain the contents of the IV, you should either save it manually or use the cipher module instead.

\param ctx DES context \param mode MBEDTLS_DES_ENCRYPT or MBEDTLS_DES_DECRYPT \param length length of the input data \param iv initialization vector (updated after use) \param input buffer holding the input data \param output buffer holding the output data

\warning DES is considered a weak cipher and its use constitutes a security risk. We recommend considering stronger ciphers instead.
