SYNOPSIS

14        #include <openssl/evp.h>
15
16        const EVP_CIPHER *EVP_ciphername(void)
17
18       EVP_ciphername is used a placeholder for any of the described cipher
19       functions, such as EVP_des_cbc.

DESCRIPTION

22       The DES encryption algorithm for EVP.
23
24       EVP_des_cbc(), EVP_des_ecb(), EVP_des_cfb(), EVP_des_cfb1(),
25       EVP_des_cfb8(), EVP_des_cfb64(), EVP_des_ofb()
26           DES in CBC, ECB, CFB with 64-bit shift, CFB with 1-bit shift, CFB
27           with 8-bit shift and OFB modes.
28
29           None of these algorithms are provided by the OpenSSL default
30           provider.  To use them it is necessary to load either the OpenSSL
31           legacy provider or another implementation.
32
33       EVP_des_ede(), EVP_des_ede_cbc(), EVP_des_ede_cfb(),
34       EVP_des_ede_cfb64(), EVP_des_ede_ecb(), EVP_des_ede_ofb()
35           Two key triple DES in ECB, CBC, CFB with 64-bit shift and OFB
36           modes.
37
38       EVP_des_ede3(), EVP_des_ede3_cbc(), EVP_des_ede3_cfb(),
39       EVP_des_ede3_cfb1(), EVP_des_ede3_cfb8(), EVP_des_ede3_cfb64(),
40       EVP_des_ede3_ecb(), EVP_des_ede3_ofb()
41           Three-key triple DES in ECB, CBC, CFB with 64-bit shift, CFB with
42           1-bit shift, CFB with 8-bit shift and OFB modes.
43
44       EVP_des_ede3_wrap()
45           Triple-DES key wrap according to RFC 3217 Section 3.

NOTES

48       Developers should be aware of the negative performance implications of
49       calling these functions multiple times and should consider using
50       EVP_CIPHER_fetch(3) instead.  See "Performance" in crypto(7) for
51       further information.
52

RETURN VALUES

54       These functions return an EVP_CIPHER structure that contains the
55       implementation of the symmetric cipher. See EVP_CIPHER_meth_new(3) for
56       details of the EVP_CIPHER structure.
