SYNOPSIS

10        #include <openssl/evp.h>
11
12        const EVP_CIPHER *EVP_seed_cbc(void);
13        const EVP_CIPHER *EVP_seed_cfb(void);
14        const EVP_CIPHER *EVP_seed_cfb128(void);
15        const EVP_CIPHER *EVP_seed_ecb(void);
16        const EVP_CIPHER *EVP_seed_ofb(void);

DESCRIPTION

19       The SEED encryption algorithm for EVP.
20
21       All modes below use a key length of 128 bits and acts on blocks of
22       128-bits.
23
24       EVP_seed_cbc(), EVP_seed_cfb(), EVP_seed_cfb128(), EVP_seed_ecb(),
25       EVP_seed_ofb()
26           The SEED encryption algorithm in CBC, CFB, ECB and OFB modes
27           respectively.

NOTES

30       Developers should be aware of the negative performance implications of
31       calling these functions multiple times and should consider using
32       EVP_CIPHER_fetch(3) instead.  See "Performance" in crypto(7) for
33       further information.
34

RETURN VALUES

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