# GmSSL-Java

A simple GmSSL encapsulation for Java developers.

## 1. Introduction

In order to benchmark international cryptographic algorithms, the SM series of algorithms have been developed in China, commonly used including SM1/SM2/SM3/SM4/SM9. 

- SM1 is a block cipher algorithm. The details of the algorithm are not disclosed at present. It is implemented by qualified manufacturers in hardware - that is, there is no software implementation. It mainly provides services in the form of encryption cards. 
- SM2 (GB/T 32918-2016) is a public key cryptography algorithm (also known as asymmetric encryption algorithm) that can partially replace RSA. 
- SM3 (GB/T 32905-2016) is a cryptographic hash algorithm that can replace MD5/SHA1/SHA256. 
- SM4 (GB/T 32907-2016) is a block cipher algorithm, which can replace AES/DES. 
- SM9 is an identity based cryptographic algorithm used for SSL VPN, which can establish an identity system similar to PKI/CA.

In this project, we mainly used Java language to encapsulate SM2, SM3, and SM4.

## 2. Environment
