Multiple GitHub accounts (Work vs Personal)

This setup uses some tricks to ensure that the right email/name/ssh-key is used for the right repos without having to think about it ever again.

  • First generate two SSH keys, ~/.ssh/id_ed25519 and ~/.ssh/id_ed25519_work
  • Add one key to your personal account and the other to your work account

.ssh/config

                Encrypt data using JavaScript in browser with RSA public key generated in C# without library
              
          

        

      

        

  

      

    
This is an example to demo how you generate the RSA key pair from server side(.NetCore 3.1) and pass the public key to the client(Browser) for encrypting the data that <= 245 bytes.




RSA-2048 can only support to encrypt up to 245 bytes data.




Generate RSA key pair in C# (.Net Core 3.1):


using var rsaProvider = new RSACng();
// spki is used for browser side encryption
var spki = Convert.ToBase64String(rsaProvider.ExportSubjectPublicKeyInfo());
var encodedPrivateKey = Convert.ToBase64String(rsaProvider.ExportPkcs8PrivateKey());
