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(3), 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.
