       - EVP DES cipher

LIBRARY
       libcrypto, -lcrypto

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_ofb()
           DES in CBC, ECB, CFB with 128-bit shift, CFB with 1-bit shift, CFB
           with 8-bit shift and OFB modes respectively.

       EVP_des_ede(), EVP_des_ede_cbc(), EVP_des_ede_ofb(), EVP_des_ede_cfb()
           Two key triple DES in ECB, CBC, CFB and OFB modes respectively.

       EVP_des_ede3(), EVP_des_ede3_cbc(), EVP_des_ede3_cfb(),
       EVP_des_ede3_cfb1(), EVP_des_ede3_cfb8(), EVP_des_ede3_ofb()
           Three-key triple DES in ECB, CBC, CFB with 128-bit shift, CFB with
           1-bit shift, CFB with 8-bit shift and OFB modes respectively.

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

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.
