如何在.net中创建一个全新的x509Certificate2？ [英] how to create a completely new x509Certificate2 in .net?

问题描述

我通过网络对其进行了搜索，找到了许多示例来从.net中的文件生成一个新的x509Certificate2，但是没有一个示例来演示如何从.net的开头生成一个全新的x509Certificate2。

I google it from web, find many samples to generate a new x509Certificate2 from a file in .net, but there is no one sample to show how to generate a completely new x509Certificate2 from the beginning in .net.

有没有人可以告诉我如何在.net中做到这一点？

Is there any one that can tell me how to do it in .net?

非常感谢。

推荐答案

以下是您可以使用的代码：

Here's a code you can use:

    static X509Certificate2 GenerateCertificate(string certName)
    {
        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.MaxValue);
        gen.SetNotBefore(DateTime.Now.Subtract(new TimeSpan(7, 0, 0, 0)));
        gen.SetSignatureAlgorithm("MD5WithRSA");
        gen.SetPublicKey(keypair.Public);           

        var newCert = gen.Generate(keypair.Private);

        return new X509Certificate2(DotNetUtilities.ToX509Certificate((Org.BouncyCastle.X509.X509Certificate)newCert));
    }

要使此功能有效，请不要忘记添加对 BouncyCastle库

for this to work, don't forget to add reference to BouncyCastle library
