RSA Key Generator

RSA Key Generator is a tiny and portable software program that enables you to generate RSA keys on the spot after filling out some simple details. These keys can be further used to enhance the security of your SSH server.

Since there is no setup pack involved, you can drop the program files in any part of the hard drive and just click the executable to launch RSA Key Generator. Another possibility is to save it to a pen drive or other removable storage unit, in order to run it on any PC with minimum effort and no previous installers.

Worth mentioning is that, unlike most installers, RSA Key Generator does not modify Windows registry settings or create extra files on the HDD without your permission, thus leaving no traces behind after its removal.

The GUI is user-friendly, represented by a small window that provides direct access to all available options. As previously mentioned, you have to fill in some simple details to generate the RSA keys.

These include the name and key prefix, NYM name, key expiration (1, 2 or 3 years), key length and passphrase (should be over 27 characters).

The key can be generated with one click, and RSA Key Generator pops up a console window to show you gathered information. It is also possible to export the public key to a pubkey.asc file.

As expected, the tool did not put a strain on computer performance throughout our evaluation, thanks to the fact that it needed a low amount of CPU and RAM to work properly. It compiled RSA keys in reasonable time and did not cause the operating system to hang, crash or pop up error messages.

Although it is not particularly feature-rich, RSA Key Generator delivers a simple solution to generating RSA keys for SSH servers, and it can be easily handled.
