I very often need md5 hash in my day to day development works. I used to use php or python to generate the md5 hashes by writing a short script.
Today, while trying .NET, I built a GUI tool to generate md5 hash and base64 encoded strings on the fly. The app requires .NET framework 3.5 SP1. It’ll run fine on Windows 7 (and Windows Vista as well, I think) without any additional installations. On earlier systems, you may be required to install .NET framework. You can use it on Linux or Mac via Mono (though I haven’t tested it myself).
I have plans to extend the program and open the source. Will do sometime soon.
Download, Install and give me feedback! 🙂
