EVP DES cipher
#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.
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.
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.
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.
