I have been testing Bouncy Castle in C#. I have not found a way to export a Pkcs10CertificationRequest object to a .pem file. I have tried with PemWriter objects but I have not succeeded. It can be the code or some idea of how to do it. Can someone help me. Thank you
You don't mention what version of BC you are using, but at least in recent versions it is directly supported by PemWriter:
Pkcs10CertificationRequest pkcs10 = ...;
FileStream file = ...;
using (var w = new Org.BouncyCastle.OpenSsl.PemWriter(new StreamWriter(file)))
{
w.WriteObject(pkcs10);
}
