充气城堡，RSA：转化成关键字符串格式 [英] Bouncy Castle, RSA: transforming keys into a String format

问题描述

我在我的C＃项目使用RSA（充气城堡API）。我产生这种方法的密钥对：

I'm using RSA (Bouncy Castle API) in my C# project. I generated the keypair with this method:

RsaKeyPairGenerator r = new RsaKeyPairGenerator();
r.Init(new KeyGenerationParameters(new SecureRandom(), 1024));
AsymmetricCipherKeyPair keys = r.GenerateKeyPair();

AsymmetricKeyParameter private_key = keys.Private;
AsymmetricKeyParameter public_key = keys.Public;

现在我想将它们保存在一个txt文件，但问题是，我无法将它们转换为字符串格式。我在那个密钥必须使用序列化另一篇文章阅读：

Now I want to save them in a txt file but the problem is that I can't convert them to a string format. I read in another post that keys must be serialized using:

PrivateKeyInfo k = PrivateKeyInfoFactory.CreatePrivateKeyInfo(private_key);
byte[] serializedKey = k.ToAsn1Object().GetDerEncoded();

这是不是正确的方式？如果是的话，我应该在此之后呢？ ？只是从byte []将它们转换为字符串

Is it the right way? If yes, what should I do after this? Just convert them from byte[] to String?

推荐答案

您也可以使用PemWriter将它们存储在PEM格式为：

You could also use PemWriter to store them in PEM format:

TextWriter textWriter = new StringWriter();
PemWriter pemWriter = new PemWriter(textWriter);
pemWriter.WriteObject(keys.Private);
pemWriter.Writer.Flush();

string privateKey = textWriter.ToString();

现在的 privateKey 包含这样的：

-----BEGIN RSA PRIVATE KEY-----
