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.
