I created an SSH key with PuTTY and can use it to successfully login to my droplet.
I tried to change the SSH key passphrase with
ssh-keygen -p Enter file in which the key is (/root/.ssh/id_rsa): /root/.ssh/authorized_keys Failed to load key /root/.ssh/authorized_keys: invalid format
The content of /root/.ssh/authorized_keys file is exactly the same as that generated by PuTTYgen (Public key for pasting into OpenSSH authorized_keys file).
does anyone know why its invalid of am I doing something wrong? or better still can I debug this?

ok thanks. Can I just make sure I’ve got this right …
I created an SSH key with PuTTY, added the public key to my droplet and can use it to successfully login to my droplet.
I was told I could update the passphrase of the key with “ssh-keygen -p” and when I run this command it asks “Enter file in which the key is (/root/.ssh/idrsa)”
when I enter “/root/.ssh/authorized_keys” I get “Failed to load key /root/.ssh/authorized_keys: invalid format”
but the content of /root/.ssh/authorized_keys file is exactly the same as that generated by PuTTYgen (Public key for pasting into OpenSSH authorized_keys file).
so maybe I’ve misunderstood what’s happening?
“When you run the command ssh-keygen -p it regenerates the key” I can’t run ssh-keygen -p becuase I get "“Failed to load key /root/.ssh/authorized_keys: invalid format”
“Check your public and private key, they should be different that what they where before.” If I get it to run, where will it place the new public & private keys?
Hi @helloSquid,
When you run the command ssh-keygen-p it regenerates the key. Check your public and private key, they should be different that what they where before.
In that case, to resolve the issue try to re-add the public ssh key to your ~/.ssh/authorized_keys file.
