What is a PPK file?

PPK files have multiple uses, and PuTTY Private Key is one of them. Read more about the other uses further down the page.

PuTTY Private Key File

.PPK PuTTY Private Key Files store the private portion of a key pair used for SSH authentication. They are used in conjunction with PuTTY, a popular Windows SSH client, to establish secure connections to remote servers.

These files are an alternative to the more commonly used OpenSSH format, which uses .pem files.

When generating a key pair, it is important to keep the private key safe, as it is used to authenticate the client to the server. Failure to secure the private key can result in unauthorized access to the server.

It is recomended to use a passphrase to encrypt the private key. This will add an extra layer of security.
