EVP_desx_cbc3ssl

Usage

 #include <openssl/evp.h>
 const EVP_CIPHER *EVP_desx_cbc(void);

Overview

The DES-X encryption algorithm for EVP.

All modes below use a key length of 128 bits and acts on blocks of 128-bits.

EVP_desx_cbc()

The DES-X algorithm in CBC mode.

This algorithm is not provided by the OpenSSL default provider. To use it is necessary to load either the OpenSSL legacy provider or another implementation.

Developers should be aware of the negative performance implications of calling this function multiple times and should consider using EVP_CIPHER_fetch(3) with EVP_CIPHER-DES(7) instead. See "Performance" in crypto(7) for further information.

Return values

These functions return an EVP_CIPHER structure that contains the implementation of the symmetric cipher. See EVP_CIPHER_meth_new(3) for details of the EVP_CIPHER structure.
