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.

       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.

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.
