SYNOPSIS

        #include <openssl/evp.h>

        const EVP_CIPHER *EVP_ciphername(void)

       EVP_ciphername is used a placeholder for any of the described cipher
       functions, such as EVP_des_cbc.


DESCRIPTION

       The DES encryption algorithm for EVP.

       EVP_des_cbc(), EVP_des_ecb(), EVP_des_cfb(), EVP_des_cfb1(),
       EVP_des_cfb8(), EVP_des_cfb64(), EVP_des_ofb()
           DES in CBC, ECB, CFB with 64-bit shift, CFB with 1-bit shift, CFB
           with 8-bit shift and OFB modes.

           None of these algorithms are provided by the OpenSSL default
           provider.  To use them it is necessary to load either the OpenSSL
           legacy provider or another implementation.

       EVP_des_ede(), EVP_des_ede_cbc(), EVP_des_ede_cfb(),
       EVP_des_ede_cfb64(), EVP_des_ede_ecb(), EVP_des_ede_ofb()
           Two key triple DES in ECB, CBC, CFB with 64-bit shift and OFB
           modes.

       EVP_des_ede3(), EVP_des_ede3_cbc(), EVP_des_ede3_cfb(),
       EVP_des_ede3_cfb1(), EVP_des_ede3_cfb8(), EVP_des_ede3_cfb64(),
       EVP_des_ede3_ecb(), EVP_des_ede3_ofb()
           Three-key triple DES in ECB, CBC, CFB with 64-bit shift, CFB with
           1-bit shift, CFB with 8-bit shift and OFB modes.

       EVP_des_ede3_wrap()
           Triple-DES key wrap according to RFC 3217 Section 3.


NOTES

       Developers should be aware of the negative performance implications of
       calling these functions 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.
