OpenSSL-SM
|
|
==========
|
|
|
|
The OpenSSL integrated with Chinese national cryptography standard:
|
|
|
|
* SM2: Elliptic curve cryptography, including signature scheme, encryption and key agreement.
|
|
* SM3: Hash algorithm with 256-bit digest length.
|
|
* SM4: or SMS4, a Feistel-style block cipher with 128-bit key length and 128-bit block size.
|
|
|
|
The first release only add SM2 signature scheme, which modify the ECDSA implementation of OpenSSL.
|
|
In the future release the SM2 will be changed to stand alone METHOD modules.
|
|
SM3 will be provided as a EVP_MD() module and SM4 will be provided as multiple EVP_CIPHER() modules.
