SYNOPSIS

10        #include <openssl/evp.h>
11
12        const EVP_CIPHER *EVP_bf_cbc(void);
13        const EVP_CIPHER *EVP_bf_cfb(void);
14        const EVP_CIPHER *EVP_bf_cfb64(void);
15        const EVP_CIPHER *EVP_bf_ecb(void);
16        const EVP_CIPHER *EVP_bf_ofb(void);

DESCRIPTION

19       The Blowfish encryption algorithm for EVP.
20
21       This is a variable key length cipher.
22
23       EVP_bf_cbc(), EVP_bf_cfb(), EVP_bf_cfb64(), EVP_bf_ecb(), EVP_bf_ofb()
24           Blowfish encryption algorithm in CBC, CFB, ECB and OFB modes
25           respectively.
26

NOTES

28       Developers should be aware of the negative performance implications of
29       calling these functions multiple times and should consider using
30       EVP_CIPHER_fetch(3) instead.  See "Performance" in crypto(7) for
31       further information.
32

RETURN VALUES

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