EVP_desx_cbc(3)                     OpenSSL                    EVP_desx_cbc(3)




NAME

       EVP_desx_cbc - EVP DES-X cipher


SYNOPSIS

        #include <openssl/evp.h>

        const EVP_CIPHER *EVP_desx_cbc(void);


DESCRIPTION

       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.
