How to create a Key Pair?

  1. To create a new Key Pair, go to the Key Pairs section and click Create.  
  2. Enter a name for the Key Pair.  
  3. If you have your own public key, enter it in the corresponding field. Otherwise, leave the field empty to generate a new Key Pair with a newly created public key.

Important: All Linux distributions (except cirrOS, which does not support ed25519) support public keys in the following formats:  

- ecdsa-sha2-nistp256  
- ecdsa-sha2-nistp384  
- ecdsa-sha2-nistp521  
- ed25519  
- rsa  

Windows Server images support only rsa-formatted public keys, and only if they were generated using the command ssh-keygen -t rsa -m pem or created through the immers.cloud web interface.

If the public key is in an unsupported format, the Key Pair will still be created, but you will not be able to decrypt the password using the private key.

You can also create a Key Pair automatically when creating a Virtual Machine, in the Key Pair field, select Create new Key Pair.
