On its own, PuTTYgen is a very useful advanced networking and security tool that can create both public and private keys for many security standards, with advanced options for setting up the strength of the key and much more.

While PuTTYgen comes in a package with Telnet client and some other 3rd party software, some users require its standalone usage, and for them, creators of PuTTY have provided it as a standalone installation. It provides an added service to the complete PuTTY package by creating RSA and DSA keys for use with the OpenSSH authorized keys files. PuTTYgen, also known as PuTTY Key Generator is a component of PuTTY, a widely known free and open-source terminal emulator, serial console, and network file transfer application that is today used all over the world by advanced users.
