DBeaver Invalid Private Key

private key genereated by ssh-keygen starts with

-----BEGIN OPENSSH PRIVATE KEY-----

and not

-----BEGIN RSA PRIVATE KEY-----

and this is not supported by DBeaver.

To generated supported key add -m PEM to the end of your ssh-keygen command

e.g.

ssh-keygen -t rsa -b 2048 -m PEM

Run this on your key to convert it to RSA private key.

ssh-keygen -p -m PEM -f ~/.ssh/id_rsa
