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.

When To Roll Your Own X
I failed to notice the relevant Wycheproof test vectors because they weren’t listed on the front page (they still aren’t).

Automated Tests Are the Safety Net that Saves You
When I wrote the Monocypher cryptographic library, I didn't really know how to write serous tests. With some help, I eventually got something pretty good, with 100% code and path coverage, that test every possible input lengths as well as obscure corner cases I stole from various places (most notably Whycheproof).

An Illustrated Guide to Elliptic Curve Cryptography Validation
Thankfully, Curve25519 is much easier to implement, with much fewer death traps than short Weierstraß curves. For X25519, just follow DJB’s advice from ECC Hacks https://www.youtube.com/watch?v=vEt-D8xZmgE and make sure your arithmetic is up to snuff (constant time arithmetic is actually the hard part, by default I strongly suggest you steal it from the ref10 implementation).
For EdDSA, just follow the relevant explicit formulas, avoid clever (but dangerous) tricks such as converting to Montgomery form and back, and test with Wycheproof’s Ed25519 test vectors. https://github.com/google/wycheproof/blob/master/testvectors...
