Using Base64 encoded Public Key to verify RSA signature

Question

In a nutshell, this is my problem:

private string publicKeyString = \"MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDVGUzbydMZS+fnkGTsUkDKEyFOGwghR234d5GjPnMIC0RFtXt         


        

Answer 1

If your partner also uses .NET, he/she can derive from Mono's makecert https://github.com/mono/mono/blob/bf55818da11240bd108dc51b374fae3d3b5482ce/mcs/tools/security/makecert.cs to generate certificate files and send to you directly.

In that case, you can easily load certificates instead of raw bytes,
