EVP_bf_cbc.3ossl - Man Page

EVP Blowfish cipher


 #include <openssl/evp.h>

 const EVP_CIPHER *EVP_bf_cbc(void);
 const EVP_CIPHER *EVP_bf_cfb(void);
 const EVP_CIPHER *EVP_bf_cfb64(void);
 const EVP_CIPHER *EVP_bf_ecb(void);
 const EVP_CIPHER *EVP_bf_ofb(void);


The Blowfish encryption algorithm for EVP.

This is a variable key length cipher.

EVP_bf_cbc(),  EVP_bf_cfb(),  EVP_bf_cfb64(),  EVP_bf_ecb(),  EVP_bf_ofb()

Blowfish encryption algorithm in CBC, CFB, ECB and OFB modes respectively.


Developers should be aware of the negative performance implications of calling these functions multiple times and should consider using EVP_CIPHER_fetch(3) with EVP_CIPHER-BLOWFISH(7) instead. See "Performance" in crypto(7) for further information.

Return Values

These functions return an EVP_CIPHER structure that contains the implementation of the symmetric cipher. See EVP_CIPHER_meth_new(3) for details of the EVP_CIPHER structure.
