CIPHER LISTING
==============

All algorithms have a fixed key length unless otherwise stated. 

EVP_enc_null()
Null cipher: does nothing. 

EVP_des_cbc(void), EVP_des_ecb(void), EVP_des_cfb(void), EVP_des_ofb(void)
DES in CBC, ECB, CFB and OFB modes respectively. 

EVP_des_ede_cbc(void), EVP_des_ede(), EVP_des_ede_ofb(void), EVP_des_ede_cfb(void)
Two key triple DES in CBC, ECB, CFB and OFB modes respectively. 

EVP_des_ede3_cbc(void), EVP_des_ede3(), EVP_des_ede3_ofb(void), EVP_des_ede3_cfb(void)
Three key triple DES in CBC, ECB, CFB and OFB modes respectively. 

EVP_desx_cbc(void)
DESX algorithm in CBC mode. 

EVP_rc4(void)
RC4 stream cipher. This is a variable key length cipher with default key length 128 bits. 

EVP_rc4_40(void)
RC4 stream cipher with 40 bit key length. This is obsolete and new code should 
use EVP_rc4() and the EVP_CIPHER_CTX_set_key_length() function. 

EVP_idea_cbc() EVP_idea_ecb(void), EVP_idea_cfb(void), EVP_idea_ofb(void), EVP_idea_cbc(void)
IDEA encryption algorithm in CBC, ECB, CFB and OFB modes respectively. 

EVP_rc2_cbc(void), EVP_rc2_ecb(void), EVP_rc2_cfb(void), EVP_rc2_ofb(void)
RC2 encryption algorithm in CBC, ECB, CFB and OFB modes respectively. This is a 
variable key length cipher with an additional parameter called ``effective key 
bits'' or ``effective key length''. By default both are set to 128 bits. 

EVP_rc2_40_cbc(void), EVP_rc2_64_cbc(void)
RC2 algorithm in CBC mode with a default key length and effective key length of 
40 and 64 bits. These are obsolete and new code should use EVP_rc2_cbc(), 
EVP_CIPHER_CTX_set_key_length() and EVP_CIPHER_CTX_ctrl() to set the key length and effective key length. 

EVP_bf_cbc(void), EVP_bf_ecb(void), EVP_bf_cfb(void), EVP_bf_ofb(void);
Blowfish encryption algorithm in CBC, ECB, CFB and OFB modes respectively. 
This is a variable key length cipher. 

EVP_cast5_cbc(void), EVP_cast5_ecb(void), EVP_cast5_cfb(void), EVP_cast5_ofb(void)
CAST encryption algorithm in CBC, ECB, CFB and OFB modes respectively. 
This is a variable key length cipher. 

EVP_rc5_32_12_16_cbc(void), EVP_rc5_32_12_16_ecb(void), EVP_rc5_32_12_16_cfb(void), EVP_rc5_32_12_16_ofb(void)
RC5 encryption algorithm in CBC, ECB, CFB and OFB modes respectively. 
This is a variable key length cipher with an additional ``number of rounds'' 
parameter. By default the key length is set to 128 bits and 12 rounds.
