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.

Sunlight, a Certificate Transparency log implementation
This is one of the projects I've been most excited about in the last few years. It let me backport to Certificate Transparency a lot of the modern transparency logging designs that came after it.
Beyond the Let's Encrypt announcement and the ct-policy thread (which includes a technical and advantages summary), here are a few resources that might be interesting.
- Design document https://filippo.io/a-different-CT-log
- Implementation https://github.com/FiloSottile/sunlight
- API specification https://c2sp.org/sunlight
- Website, including test logs and feedback channels https://sunlight.dev/
If you’re thinking “oh we could use something similar” please reach out! Sunlight is retrofitting some of the modern tlog designs on a legacy system. With a greenfield deployment you can do even better! I’m working with the Sigsum project on specs, tooling, and a support ecosystem to make deploying tlogs easier and safer.

Do any libraries exist for zero-trust file storage (storing client-encrypted data on the server without the key)?

argon2 vs bcrypt vs scrypt vs pbkdf2
Argon2 is the best choice, but scrypt may be more easily available: https://github.com/C2SP/C2SP/issues/10

Age: Modern file encryption format with multiple pluggable recipients
Hi! I read and appreciated your issues and discussions, sorry I didn't get to respond to them yet, but I've been thinking about it.
Although I don't disagree that parsing text is hard, I also think that parsing variable-size binary formats is hard (and there is a tall, tall pile of bugs to confirm that). Really, parsing is hard. Rather than count on one design or the other to be bug-proof, I worked on a large test suite to help implementations catch their parsing bugs. [https://c2sp.org/CCTV/age] I think it would have found one of the issues you reported if that implementation had integrated it, and I am going to add vectors for various resource exhaustion scenarios which I hope would have found the other. (I am not going to look at what it is exactly, so I will know if I made the suite comprehensive enough without being too specific about this bug.)
I also liked your observation that it would have been nice if the header was streamable. [https://github.com/C2SP/C2SP/issues/28] It went on the pile labeled "regrets / for v2 when it comes", thank you.

age.el: age encryption support for Emacs
I think it's ironic that you imply a "dozen of immature crypto libraries" are used in the Age spec. It's quite the opposite and the Age spec provides a reduction in so-called "yolo crypto" versus the OpenPGP spec. See: https://github.com/C2SP/C2SP/blob/main/age.md and also give https://latacora.micro.blog/2019/07/16/the-pgp-problem.html# for a pretty accurate overview of what's wrong with OpenPGP.

Pa – a simple password manager based on age
… okay, then look at the spec, which is beautifully simple: https://github.com/C2SP/C2SP/blob/main/age.md#the-scrypt-rec...
- The recent security issues with LastPass made me wonder - couldn't I just use an encrypted notepad app on my phone to achieve the same level of security?

Age WASM - age encryption tool in the browser
I had the same question. I believe it refers to “Actually Good Encryption” (https://github.com/C2SP/C2SP/blob/main/age.md).
What are some alternatives?
sops - Simple and flexible tool for managing secrets
age.el - Transparent age encryption support for Emacs modeled after EPG/EPA
age - A simple, modern and secure encryption tool (and Go library) with small explicit keys, no config options, and UNIX-style composability.
pa - a simple password manager. encryption via age, written in portable posix shell
rage - A simple, secure and modern file encryption tool (and Rust library) with small explicit keys, no config options, and UNIX-style composability.
passage - A fork of password-store (https://www.passwordstore.org) that uses age (https://age-encryption.org) as backend.
