About PEM and PPK Formats
PEM (Privacy Enhanced Mail) is a base64 encoded format commonly used for certificates and private keys in OpenSSL and many Unix/Linux systems. It's the standard format for keys generated with OpenSSH.
PPK (PuTTY Private Key) is a proprietary format used by PuTTY, a popular SSH client for Windows. Converting PEM to PPK allows you to use keys generated on Unix/Linux systems with PuTTY on Windows.
