There is a C# program that works with SSH connection. It works with clients who use .ppk keys generated by PuTTY. However, the library SSH.NET works only with OpenSSH keys. Of course, you can use puttygen, but it would be too difficult for users. I would like to do the same thing that puttygen does, but inside my program.
I probably need to understand the structure of RSA in more detail. I will be glad if you can advise useful resources.
