BouncyCastle的PrivateKey要X509Certificate2 PrivateKey

本文介绍了BouncyCastle的PrivateKey要X509Certificate2 PrivateKey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

我创建使用BouncyCastle的证书

I create a certificate using BouncyCastle

var keypairgen = new RsaKeyPairGenerator(); keypairgen.Init(new KeyGenerationParameters(new SecureRandom(new CryptoApiRandomGenerator()), 1024)); var keypair = keypairgen.GenerateKeyPair(); var gen = new X509V3CertificateGenerator(); var CN = new X509Name("CN=" + certName); var SN = BigInteger.ProbablePrime(120, new Random()); gen.SetSerialNumber(SN); gen.SetSubjectDN(CN); gen.SetIssuerDN(CN); gen.SetNotAfter(DateTime.Now.AddYears(1)); gen.SetNotBefore(DateTime.Now.Subtract(new TimeSpan(7,0,0,0))); gen.SetSignatureAlgorithm("MD5WithRSA"); gen.SetPublicKey(keypair.Public); gen.AddExtension( X509Extensions.AuthorityKeyIdentifier.Id, false, new AuthorityKeyIdentifier( SubjectPublicKeyInfoFactory.CreateSubjectPublicKeyInfo(keypair.Public), new GeneralNames(new GeneralName(CN)), SN )); gen.AddExtension( X509Extensions.ExtendedKeyUsage.Id, false, new ExtendedKeyUsage(new ArrayList() { new DerObjectIdentifier("1.3.6.1.5.5.7.3.1") })); var newCert = gen.Generate(keypair.Private);

本月底与

X509Certificate2 certificate = new X509Certificate2(DotNetUtilities.ToX509Certificate((Org.BouncyCastle.X509.X509Certificate)newCert));

现在，因为我的任务告诉我，来存储证书和PrivateKey在我需要一种方法来转换keypair.Private成X509Certificate2.Private的X509Certificate2对象。任何想法？

Now, because my assignment tells me to store both the Certificate and the PrivateKey in the X509Certificate2 object I need a way to convert the keypair.Private into a X509Certificate2.Private. Any ideas?

感谢。

推荐答案

如果你从this问题，你应该能够使用类似的东西来 DotNetUtilities.ToRSA（...）键，把它的返回值到 X509Certificate2 的 PrivateKey 。

If you look at the links from this question, you should be able to use something similar to DotNetUtilities.ToRSA(...) and put its return value into the X509Certificate2's PrivateKey.
