## Features
* Support Chinese
* BSD-style license
* Full support of Chinese GM Cryptography Standards
* Support Chinese cryptographic hardwares (HSMs).
* Commercial friendly BSD-style open source license.
- Support [Chinese GM/T cryptographic standards](http://gmssl.org/docs/standards.html).
- Support [hardware cryptographic modules from Chinese vendors](http://www.sca.gov.cn/sca/zxfw/cpxx.shtml).
- With commercial friendly open source [license](http://gmssl.org/docs/licenses.html).
## Supported Algorithms
## GM/T Algorithms
- **SM3** cryptographic hash function with 256-bit digest length specified in GM/T 0004-2012.
- **SM4** block cipher with 128-bit key length and 128-bit block size specified in GM/T 0002-2012.
- **SM2** elliptic curve cryptographic schemes including digital signature scheme, public key encryption, (authenticated) key exchange protocol and one recommended 256-bit prime field curve specified in GM/T 0003-2012.
- **SM9** pairing-based cryptographic schemes including identity-based digital signature, encryption, (authenticated) key exchange protocol and one 256-bit recommended BN curve, defined in GM/T 0046-2016.
- **ZUC** stream cipher, **128-EEA3** encryption algorithm and **128-EIA3** integrity algorithm specified in GM/T 0001-2012.
- **SM1** and **SSF33** block ciphers with 128-bit key length and 128-bit block size without public specification, only provided with chip.
GmSSL will support all the following GM/T cryptographic algorithms:
## GM/T SSL Protocol
- SM3 (GM/T 0004-2012): cryptographic hash function with 256-bit digest length.
- SM4 (GM/T 0002-2012): block cipher with 128-bit key length and 128-bit block size, also named SMS4.
- SM2 (GM/T 0003-2012): elliptic curve cryptographic schemes including digital signature scheme, public key encryption, (authenticated) key exchange protocol and one recommended 256-bit prime field curve `sm2p256v1`.
- SM9 (GM/T 0044-2016): pairing-based cryptographic schemes including identity-based digital signature, encryption, (authenticated) key exchange protocol and one 256-bit recommended BN curve.
- ZUC (GM/T 0001-2012): stream cipher, with 128-EEA3 encryption algorithm and 128-EIA3 integrity algorithm.
- SM1 and SSF33: block ciphers with 128-bit key length and 128-bit block size without public specification, only provided with chip.
GmSSL supports many useful cryptographic algorithms and schemes:
- Public-key schemes: Paillier, ECIES (Elliptic Curve Integrated Encryption Scheme)
- Pairing-based cryptography: BF-IBE, BB1-IBE
- Block ciphers and modes: Serpent, Speck
- Block cipher modes: FPE (Format-Preserver Encryption)
- Encoding: Base58
OpenSSL algorithms such as ECDSA, RSA, AES, SHA-1 are all remained in GmSSL.
