如何从.NET中读取PEM RSA私钥

问题描述：

我有一个 RSA 私钥在 PEM 格式，有一个直接的方式来阅读从.NET和实例化 RSACryptoServiceProvider 以解密用相应的公钥加密的数据？

I've got an RSA private key in PEM format, is there a straight forward way to read that from .NET and instantiate an RSACryptoServiceProvider to decrypt data encrypted with the corresponding public key?

答

我解决了，谢谢。如果有人有兴趣， bouncycastle 做了，戏弄，只是花了我一些时间，由于缺乏知识从我的侧面和文档。这是代码：

I solved, thanks. In case anyone's interested, bouncycastle did the trick, just took me some time due to lack of knowledge from on my side and documentation. This is the code:

var bytesToDecrypt = Convert.FromBase64String("la0Cz.....D43g=="); // string to decrypt, base64 encoded

AsymmetricCipherKeyPair keyPair; 

using (var reader = File.OpenText(@"c:\myprivatekey.pem")) // file containing RSA PKCS1 private key
    keyPair = (AsymmetricCipherKeyPair) new PemReader(reader).ReadObject(); 

var decryptEngine = new Pkcs1Encoding(new RsaEngine());
decryptEngine.Init(false, keyPair.Private); 

var decrypted = Encoding.UTF8.GetString(decryptEngine.ProcessBlock(bytesToDecrypt, 0, bytesToDecrypt.Length));
