For example, using standard computing power it may take over a million years to crack an SSH key, but a standard password will take far less time to compromise. Using SSH keys is more secure than passwords as they are more difficult to crack compared to typical passwords. The public key is not a secret but the private key should never be shared with anyone nor uploaded to any untrusted location. The public key is what resides on the remote server and the private key is stored on your local device. A SSH key consists of two parts: a public and a private key. SSH Keys are small text files meant to be exchanged in lieu of passwords for verifying access to a remote server.
