Reading RSA Private Key in PEM format And Reading

问题:

I'm trying to use a PEM(X.509) certificate (stored in a privateKey.pem file on disk) to sign messages.After that i need to verify signature by using certificate (sent to the receiver). Help with this, especially example code in c# and RSA algorithm

回答1:

You may find the Bouncycastle C# library to be of value in your problem. There is a PEMReader class that should be able to read in your PEM file and convert the contents to Bouncycastle cryptography objects. And there is a DotNetUtilities class to provide a bridge between Bouncycastle and .NET cryptography objects.

This is how you can sign message using x509 certificate.
