| To load an existing key, press the //Load// button. PuTTYgen will put up 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. | To load an existing key, press the //Load// button.

| Using the //Import// command from the //Conversions// menu, PuTTYgen can load SSH-2 private keys in OpenSSH's format and ssh.com's format. Once you have loaded one of these key types, you can then save it back out as a PuTTY-format key (''*.PPK'') so that you can use it with the WinSCP. The passphrase will be unchanged by this process (unless you deliberately change it). You may want to change the key comment before you save the key, since OpenSSH's SSH-2 key format contains no space for a comment and ssh.com's default comment format is long and verbose. | Using the //Import// command from the //Conversions// menu, PuTTYgen can load SSH-2 private keys in OpenSSH's format and ssh.com's format.
