35 const EVP_CIPHER *EVP_ciphername(void)
37 I<EVP_ciphername> is used a placeholder for any of the described cipher
38 functions, such as I<EVP_des_cbc>.
42 The DES encryption algorithm for EVP.
54 DES in CBC, ECB, CFB with 64-bit shift, CFB with 1-bit shift, CFB with 8-bit
57 None of these algorithms are provided by the OpenSSL default provider.
58 To use them it is necessary to load either the OpenSSL legacy provider or another
68 Two key triple DES in ECB, CBC, CFB with 64-bit shift and OFB modes.
79 Three-key triple DES in ECB, CBC, CFB with 64-bit shift, CFB with 1-bit shift,
80 CFB with 8-bit shift and OFB modes.
82 =item EVP_des_ede3_wrap()
84 Triple-DES key wrap according to RFC 3217 Section 3.
90 These functions return an B<EVP_CIPHER> structure that contains the
91 implementation of the symmetric cipher. See L<EVP_CIPHER_meth_new(3)> for
92 details of the B<EVP_CIPHER> structure.
