使用 Tongsuo 签发 SM2 双证书

SM2测试双证书

也可以直接使用 Tongsuo 项目中已经签发的SM2双证书，仅用于测试； 根CA > 中间CA > 客户端/服务端证书，根CA证书签发中间CA证书，中间CA证书签发客户端和服务端的证书，包括签名证书和加密证书，这些证书的公钥算法都是SM2。

服务端签名证书和私钥：

• https://github.com/Tongsuo-Project/Tongsuo/blob/master/test/certs/sm2/server_sign.crt
• https://github.com/Tongsuo-Project/Tongsuo/blob/master/test/certs/sm2/server_sign.key

服务端加密证书和私钥：

• https://github.com/Tongsuo-Project/Tongsuo/blob/master/test/certs/sm2/server_enc.crt
• https://github.com/Tongsuo-Project/Tongsuo/blob/master/test/certs/sm2/server_enc.key

CA证书，这里面包含根CA和中间CA证书：

• https://github.com/Tongsuo-Project/Tongsuo/blob/master/test/certs/sm2/chain-ca.crt

客户端签名证书和私钥：

• https://github.com/Tongsuo-Project/Tongsuo/blob/master/test/certs/sm2/client_sign.crt
• https://github.com/Tongsuo-Project/Tongsuo/blob/master/test/certs/sm2/client_sign.key

客户端加密证书和私钥：

• https://github.com/Tongsuo-Project/Tongsuo/blob/master/test/certs/sm2/client_enc.crt
• https://github.com/Tongsuo-Project/Tongsuo/blob/master/test/certs/sm2/client_enc.key
