| + | ===== [[authorized_keys]] Public Key for Pasting into OpenSSH authorized_keys File ===== | ||
| + | The OpenSSH server, among others, requires your public key to be given to it in a one-line format before it will accept authentication with your private key. (SSH-1 servers also used this method.) | ||
| + | |||
| + | The //Public key for pasting into OpenSSH authorized_keys file// gives the public-key data in the correct one-line format. | ||
| + | |||
| + | For more details refer to guide to [[guide_public_key|setting up public key authentication]]. | ||
| + | |||
| + | WinSCP can [[ui_login_authentication#private_key_tools|show you the public key]] too. | ||

| + | ===== [[reloading]] Reloading a Private Key ===== | ||
| + | |||
| + | PuTTYgen allows you to load an existing private key file into memory. If you do this, you can then change the passphrase and comment before saving it again; you can also make extra copies of the public key. | ||
| + | |||
| + | To load an existing key, press the //Load// button. PuTTYgen will display a dialog box where you can browse around the file system and find your key file. Once you select the file, PuTTYgen will ask you for a passphrase (if necessary) and will then display the key details in the same way as if it had just generated the key. | ||
| + | |||
| + | If you use the //Load// command to load a foreign key format, it will work, but you will see a message box warning you that the key you have loaded is not a PuTTY native key. See [[#other_formats|below]] for information about importing foreign key formats. | ||
