Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Hashing Is Not Encryption
(shameless plug) If you want to start by doing your own implementation of SHA-256, you can take a look at one of my assignments :) https://github.com/oconnor663/applied_crypto_2021_fall/tree/...

The Pinouts Book
> IIRC SHA256 outputs the full state so some types of length extension attack are still possible (though massively less _practical_ than against MD5)
I'm not aware of any differences between the length extension attack on MD5 vs the one on SHA-256. As far as I know, it works the same way on both. Here's an assignment I did on the SHA-256 version if you want a deep dive: https://github.com/oconnor663/applied_crypto_2021_fall/tree/...
It's possible you're thinking about finding collisions? It's true that this is much easier for MD5 than for SHA-256.
