The SM4 blockcipher (GB/T 32907-2016) for EVP.
All modes below use a key length of 128 bits and acts on blocks of 128 bits.
-
EVP_sm4_cbc(), EVP_sm4_ecb(),
EVP_sm4_cfb(), EVP_sm4_cfb128(), EVP_sm4_ofb(),
EVP_sm4_ctr()
- The SM4 blockcipher with a 128-bit key in CBC, ECB, CFB,
OFB and CTR 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-SM4(7) instead. See
"Performance" in
crypto(7) for further information.
These functions return a
EVP_CIPHER structure that contains the
implementation of the symmetric cipher. See
EVP_CIPHER_meth_new(3) for
details of the
EVP_CIPHER structure.
