29=head1 SYNOPSIS
30
31=for openssl generic
32
33 #include <openssl/evp.h>
34
35 const EVP_CIPHER *EVP_ciphername(void)
36
37I<EVP_ciphername> is used a placeholder for any of the described cipher
38functions, such as I<EVP_des_cbc>.
39
40=head1 DESCRIPTION
41
42The DES encryption algorithm for EVP.

46=item EVP_des_cbc(),
47EVP_des_ecb(),
48EVP_des_cfb(),
49EVP_des_cfb1(),
50EVP_des_cfb8(),
51EVP_des_cfb64(),
52EVP_des_ofb()
53
54DES in CBC, ECB, CFB with 64-bit shift, CFB with 1-bit shift, CFB with 8-bit
55shift and OFB modes.
56
57None of these algorithms are provided by the OpenSSL default provider.
58To use them it is necessary to load either the OpenSSL legacy provider or another
59implementation.

63EVP_des_ede_cfb(),
64EVP_des_ede_cfb64(),
65EVP_des_ede_ecb(),
66EVP_des_ede_ofb()
67
68Two key triple DES in ECB, CBC, CFB with 64-bit shift and OFB modes.

75EVP_des_ede3_cfb64(),
76EVP_des_ede3_ecb(),
77EVP_des_ede3_ofb()
78
79Three-key triple DES in ECB, CBC, CFB with 64-bit shift, CFB with 1-bit shift,
80CFB with 8-bit shift and OFB modes.
81
82=item EVP_des_ede3_wrap()
83
84Triple-DES key wrap according to RFC 3217 Section 3.

88=head1 RETURN VALUES
89
90These functions return an B<EVP_CIPHER> structure that contains the
91implementation of the symmetric cipher. See L<EVP_CIPHER_meth_new(3)> for
92details of the B<EVP_CIPHER> structure.
