I have a SSH2 public key with a .PUB extension and when viewed in notepad it has this header:
---- BEGIN SSH2 PUBLIC KEY ----
How do I view the thumbprint of this key?
ssh-keygen -lf key.pub but that returns: "Is not a valid key file". (I got the binaries for ssh-keygen from github's standard shell.
I'm a bit new to SSH/SSH2 and not sure what the difference is, or if I'm using the wrong version of a tool for the wrong version of a public key.
