.Sh DESCRIPTION
These functions provide the DES encryption algorithm in the
.Xr evp 3
framework.
.Pp
.Fn EVP_des_cbc ,
.Fn EVP_des_cfb1 ,
.Fn EVP_des_cfb8 ,
.Fn EVP_des_cfb64 ,
.Fn EVP_des_ecb ,
and
.Fn 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.
.Fn EVP_des_cfb
is an alias for
.Fn EVP_des_cfb64 ,
implemented as a macro.
.Pp
.Fn EVP_des_ede_cbc ,
.Fn EVP_des_ede_cfb64 ,
.Fn EVP_des_ede_ecb ,
and
.Fn EVP_des_ede_ofb
provide two key triple DES in CBC, CFB with 64-bit shift, ECB, and OFB modes.
.Fn EVP_des_ede_cfb
is an alias for
.Fn EVP_des_ede_cfb64 ,
implemented as a macro.
.Fn EVP_des_ede
is an alias for
.Fn EVP_des_ede_ecb .
.Pp
.Fn EVP_des_ede3_cbc ,
.Fn EVP_des_ede3_cfb1 ,
.Fn EVP_des_ede3_cfb8 ,
.Fn EVP_des_ede3_cfb64 ,
.Fn EVP_des_ede3_ecb ,
.Fn 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.
.Fn EVP_des_ede3_cfb
is an alias for
.Fn EVP_des_ede3_cfb64 ,
implemented as a macro.
.Fn EVP_des_ede3
is an alias for
.Fn EVP_des_ede3_ecb .
.Pp
.Fn 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.
.Sh RETURN VALUES
These functions return an
.Vt EVP_CIPHER
structure that provides the implementation of the symmetric cipher.
