Over on Github I’ve open sourced a little library for generating and verifying product registration keys. I needed this for a couple of my projects, and I’ve made it available with hopes of saving anyone else from having to write one!
The tool takes a someone’s name and a salt (which is your product id in most cases) and spits out a short upper case string of letters and numbers (minus confusing ones like o/0 1/l).
The goals of this tool are simple: to generate a short easily entered registration code without the need for an internet connection or the need for cryptographic libraries which may not be commonly available.
As a result the code the tool generates is by no means cryptographically secure, but since serious crackers can just bypass the reg-key check altogether using commonly available tools, this is really just to keep honest people honest!
Hopefully it’ll be useful to you someone…
The Simple Download Manager is another itch scratch to open source software project tale, basically I needed a simple way to serve files for download and keep some statistics. So, like a good open source citizen I’ve made it available under the GPL, hopefully it’ll save someone some time!
