DESCRIPTION
These functions provide the DES encryption algorithm in the evp(3) framework.EVP_des_cbc(),
EVP_des_cfb1(),
EVP_des_cfb8(),
EVP_des_cfb64(),
EVP_des_ecb(),
and
EVP_des_ofb()
provide DES in CBC, CFB with 1-bit shift, CFB with 8-bit shift, CFB with
64-bit shift, ECB, and OFB modes.
EVP_des_cfb()
is an alias for EVP_des_cfb64(), implemented as a
macro.
EVP_des_ede_cbc(),
EVP_des_ede_cfb64(),
EVP_des_ede_ecb(),
and
EVP_des_ede_ofb()
provide two key triple DES in CBC, CFB with 64-bit shift, ECB, and OFB
modes.
EVP_des_ede_cfb()
is an alias for EVP_des_ede_cfb64(), implemented as
a macro.
EVP_des_ede()
is an alias for EVP_des_ede_ecb().
EVP_des_ede3_cbc(),
EVP_des_ede3_cfb1(),
EVP_des_ede3_cfb8(),
EVP_des_ede3_cfb64(),
EVP_des_ede3_ecb(),
EVP_des_ede3_ofb()
provide three key triple DES in CBC, CFB with 1-bit shift, CFB with 8-bit
shift, CFB with 64-bit shift, ECB, and OFB modes.
EVP_des_ede3_cfb()
is an alias for EVP_des_ede3_cfb64(), implemented as
a macro.
EVP_des_ede3()
is an alias for EVP_des_ede3_ecb().
EVP_desx_cbc()
provides the DES-X encryption algorithm in CBC mode. It uses a key length of
128 bits and acts on blocks of 128 bits.
RETURN VALUES
These functions return an EVP_CIPHER structure that provides the implementation of the symmetric cipher.
