Converting X509Certificate2 certificate into BouncyCastle X509Certificate

Question

I have an object of System.Security.Cryptography.X509Certificates.X509Certificate2. I need to convert it into an object of Org.BouncyCastle.X509.X509Certificate.

Can anyone help me please?

Answer 1

使用Org.BouncyCastle.Security.DotNetUtilities.FromX509Certificate ，它获取System.Security.Cryptography.X509Certificates.X509Certificate并返回Org.BouncyCastle.X509.X509Certificate 。

Answer 2

It's been a while since I played with Bouncy Castle. Basically take X509Certificate2.RawData and pass it to the BC X509Certificate constructor.

If I remember correctly, BC has a Org.BouncyCastle.Security.DotNetUtilities . This should allow you to import a certificate.

Answer 3

Here is how I do that (BouncyCastle.Crypto version 1.8.1.0):

var cert = new Org.BouncyCastle.X509.X509CertificateParser()
    .ReadCertificate(x509Certificate2.GetRawCertData());

In other answers mentioned Org.BouncyCastle.Security.DotNetUtilities.FromX509Certificate(X509Certificate) works too.
