In asymmetric cryptography, a common system for encrypting data, there are two decryption tools, or ?keys.? The first is a private key that only the user knows, and the other is a public key, which is safe to share with everyone.

If your client public key is such a weak key and you publish it, then an attacker who obtains it may be able to tell so and exploit this fact. They would then be able to log in to the SSH servers that you use that key to authenticate to. That would indeed be an additional risk.

The best approach for securely authenticating SSH sessions, however, is to create a public key pair for the local computer and copy the public key file to the remote SSH server. Only a user with authenticated permission should be able to copy files to the server.

To generate an SSH private/public key pair for your use, you can use the ssh-keygen command-line utility. You can run the ssh-keygen command from the command line to generate an SSH private/public key pair. If you are using Windows, by default you may not have access to the ssh-keygen command.
