Java生成SM2证书基于BouncyCastle(cer)

本文主要是介绍Java生成SM2证书基于BouncyCastle(cer)，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

Java生成SM2证书基于BouncyCastle(cer)

可以先加QQ 783021975 咨询相关问题。

自己研究那就是看BC源码。不愿意看就看别的大佬的开源代码

https://github.com/ZZMarquis/gmhelper

【SM2证书】利用BC的X509v3CertificateBuilder组装X509国密证书

SM2、SM4加解密 SM2 SM3 签名验签代码部分开源在gitee&github

https://github.com/xiaoshuaishuai319/algorithmNation

https://gitee.com/xshuai/algorithmNation

整理中。完全是Java代码调用BouncCastle生成的哦。先来个图看下签名算法和公钥参数都是符合SM2算法的

2018年6月22日更新:CRL分布点，添加证书策略，颁发者密钥标识，使用者密钥标识，密钥用法，增强密钥用法，基本约束

需要用到的BC包
