I thought I’d throw this out there. Here’s a tool I’ve been working on the last little while:
We needed a quick and easy way to build hashes for WordPress.org plugins (as well as having the hashes for WordPress files) and so we built a way to do this and provided a simple API to access it.
And, for kicks, we also decided to include ClassicPress releases in it too. So, for example, you can get all the SHA1 file hashes for CP 1.0.1 with this link:
Bear in-mind this is very beta, but it works reliably as far as we can tell and with caching in-place, it’s pretty quick.
Happy to hear thoughts/feedback on this.
