读取PEM格式的RSA私钥并从证书中读取公钥 [英] Reading RSA Private Key in PEM format And Reading public Key from certificate

问题描述

我正在尝试使用PEM（X.509）证书（存储在磁盘上的privateKey.pem文件中）对邮件进行签名。此后，我需要使用证书（发送给接收方）来验证签名。
帮助解决此问题，尤其是c＃和RSA算法中的示例代码

I'm trying to use a PEM(X.509) certificate (stored in a privateKey.pem file on disk) to sign messages.After that i need to verify signature by using certificate (sent to the receiver). Help with this, especially example code in c# and RSA algorithm

推荐答案

您可能会找到 Bouncycastle C＃库对于解决您的问题很有价值。有一个PEMReader类应该能够读取您的PEM文件并将其内容转换为Bouncycastle加密对象。还有一个DotNetUtilities类可以在Bouncycastle和.NET加密对象之间建立桥梁。

You may find the Bouncycastle C# library to be of value in your problem. There is a PEMReader class that should be able to read in your PEM file and convert the contents to Bouncycastle cryptography objects. And there is a DotNetUtilities class to provide a bridge between Bouncycastle and .NET cryptography objects.
