C# RSA加密、解密、加签、验签、支持JAVA格式公钥私钥、PEM格式公钥私钥、.NET格式公钥私钥 -变态模式【支持私钥加密，公钥解密】（二）

2019-02-26更新：已上传github

RSA变态模式：【私钥加密，公钥解密】

一般这种写法都是JAVA弄的。.NET原生不支持。为啥，我也不清楚，大概是因为安全性问题吧，毕竟公钥是人人都可是持有的。私钥只有自己拥有。

一般方法请看：http://blog.csdn.net/gzy11/article/details/54573973

签名一直都是【私钥加签、公钥验签】只为证明该消息是你发出来的。

 

这里使用了BouncyCastle1.8.1.0 nuget包。

所有加签、加密返回结果都是base64的，注意格式换。如下：

byte[] dataBytes = Convert.FromBase64String(data);
string base64Str = Convert.ToBase64String(signer.GenerateSignature());

PEM格式秘钥，自己改了下源代码，能直接加载PEM的string格式的RSA。不用读取文件。改的有些不太合理，就不发了。
单元测试及调用方法

 //注意SHA-512WITHRSA/PSS 对应的公私钥大小，不满足需求会报错的 key is too small

Algorithms请参见GetAlgorithms()方法。这个都是从BouncyCastle源码里拿出来的。注意.NET对应的格式。

CSDN下载不靠谱，不要积分的现在下的人多了积分要那么多，谁没事老去整积分啊。要源码的可以直接留言，留下邮箱。
