Create a secure SSH authentication key in seconds.Fully featured and RSA, DSA, ECDSA, and EdDSA key generation utility.The app can also convert the key into other formats if the default one does not suit your needs. The key can be customized with a comment, and additionally secured with a passphrase. This random movement data is incorporated into the key generation, ensuring that the key is completely unique. This random data is provided in an innovative way – by randomly moving the mouse cursor across the blank area of the app. Above that, you can customize the strength of the key, including the number of bits used (the higher the better) and the random data that is needed for the generation engine. The options are RSA, DSA, ECDSA, ED25519, and SSH-1 (RSA). At the bottom, you have the primary selection area where you must specify what kind of key you wish to generate. Once fired up, you will be welcomed with the minimalistic interface that features just a single screen that’s filled with tools and customization areas. Full uninstaller is included in the package. However, the installation procedure is fairly straightforward, requiring you only to follow on-screen instructions. PuTTYgen comes in an installation package that clocks in at a massive 640 MB, and therefore its transfer to the final hard drive location can last even a few minutes if your PC hardware is on a slower side (especially if you are using an old laptop with a slow storage drive).

The app features just a single simple UI screen, with a well-organized set of options and a built-in user manual that features well-documented usage scenarios for any type of user.

One of the key strengths of this app is its simplicity, enabling power users to gain easy SSH authentication and generation of RSA and DSA keys with incredible ease. 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 64 bit 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.
