使用Bouncy Castle c＃创建CRL文件

本文介绍了使用Bouncy Castle c＃创建CRL文件的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我已经用Bouncy Castle构建了自己的根CA证书，并且正在使用它来构建其他证书。我想使用Bouncy Castle C＃构建一个证书吊销列表（CRL）以包括已吊销的证书列表。示例：

I've build my own root CA certificate with Bouncy Castle, and I'm using it to build other certificates. I want to build a Certificate Revocation List (CRL) to include the list of revoqued certificates, using Bouncy Castle C#. Example:

//Retrieve CA root certificate X509Store CAstore = new X509Store(StoreName.Root, StoreLocation.CurrentUser); CAstore.Open(OpenFlags.ReadWrite | OpenFlags.OpenExistingOnly); X509Certificate2Collection x509Certificate2Collection = CAstore.Certificates.Find(X509FindType.FindBySerialNumber, this.textBoxSerialCA.Text, true); X509Certificate2 cert = x509Certificate2Collection[0]; var certCA = DotNetUtilities.FromX509Certificate(cert); CAstore.Close(); X509V2CrlGenerator crlGen = new X509V2CrlGenerator(); crlGen.SetIssuerDN(certCA.IssuerDN); crlGen.SetThisUpdate(DateTime.Now); crlGen.SetNextUpdate(DateTime.Now.AddYears(1)); crlGen.SetSignatureAlgorithm("SHA1withRSA"); crlGen.AddCrlEntry(BigInteger.One, DateTime.Now, CrlReason.PrivilegeWithdrawn); crlGen.AddExtension(X509Extensions.AuthorityKeyIdentifier, false, new AuthorityKeyIdentifierStructure(certCA)); crlGen.AddExtension(X509Extensions.CrlNumber, false, new CrlNumber(BigInteger.One)); var randomGenerator = new CryptoApiRandomGenerator(); var random = new SecureRandom(randomGenerator); var Akp = Org.BouncyCastle.Security.DotNetUtilities.GetKeyPair(cert.PrivateKey).Private; X509Crl crlTemp = crlGen.Generate(Akp,random);

在这一点上一切正常。如何将X509Crl对象保存到.crl文件？

All is OK until this point. How can I save the X509Crl object into a .crl file?

最诚挚的问候。

推荐答案

这个答案来得很晚，但是您可以使用Bouncy Castle中的 PemWriter 类来写入PEM文件。

This answer comes quite late, but you can use the PemWriter class in Bouncy Castle to write to a PEM file.

PemWriter pemWriter = new PemWriter(new StreamWriter(File.Open(fileName, FileMode.Create))); pemWriter.WriteObject(crlTemp); pemWriter.Writer.Flush(); pemWriter.Writer.Close();
