| Public key authentication is an alternative means of identifying yourself to a login server, instead of typing a password. It is more secure and more flexible, but more difficult to set up. | Public key authentication is an alternative means of identifying yourself to a login server, instead of typing a password.

| Different file formats are used to store SSH-1 and SSH-2 private keys. While there is only one commonly used format for SSH-1 keys, there are several formats used for SSH-2 keys. WinSCP supports PuTTY format, as authors of PuTTY [[&url(keyformat)|claim that it is the best one]]. | Different file formats are used to store SSH-1 and SSH-2 private keys.

| WinSCP also recognises (but does not accept) the other two formats (OpenSSH and ssh.com), so it can suggest you to convert them.
