|
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.

|
.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 ,

|
.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.

|
.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.
