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.

A warning to always remember that Obsidian Sync is potentially dangerous
Given that the encryption algorithm is open source (https://github.com/Tarsnap/scrypt) can you try to explain what you mean here?

OpenSSL and a rookie (me)
I wouldn't use OpenSSL personally. If you just need simple but secure symmetric encryption, checkout the scrypt(1) encryption utility from Tarsnap. If you need support for public keys, check out age(1).

What is the best encryption for files?
scrypt if you strictly only need symmetric encryption.

Ask HN: Where to ask for feedback about a cryptography related tool
First of all I know that "implementing your own cryptography is bad". However, at some point, one does stumble upon a use-case that is not (well) covered by existing tools.
Now, assuming one has already done his due-diligence and has read (and hopefully understood at least the main ideas of) cryptography related articles / posts / etc. (especially in the area pertaining to what one wants to build), and thus we can assume one is not a complete newbie in this mater, however, nor is he an expert. Basically we can assume he is an "amateur".
Where would one go with his design to ask for feedback about it, in the hope to at least eliminate some weaknesses that one (as a non expert) might have overlooked. (I'm not speaking here about "proofs" or "audits".)
----
More specifically ---- but please let's not get into this right now, this being just an example ---- I'm trying to implement something similar to `scrypt` (the encryption utility, that uses the `scrypt` PBKDF, ) or `age` (), as a replacement to my current solution that relies on GnuPG.

Audacity Is Now A Possible Spyware, Remove It ASAP
It entirely does and that's exactly my point. Most "hashes" are designed to be fast, for data validation/checking whatever. For securing data (passwords, anonymisation, etc) you want a "hash" to be as slow as possible. Scrypt for example is designed to be extremely slow and use much memory (making GPU-based parallelisation useless and driving up the cost of CPU-based work). The default settings for five-second hashes changes their 18 hour estimate to a bit over two years... and that's assuming you don't turn it up further.

How secure is it to encrypt a file using 7zip? Can nobody really access the files without knowing the password?
Even if that were to happen, you can run the page locally. Also the entire source is available on github https://github.com/sh-dv/hat.sh

Hat.sh V2 release - simple, fast, secure client-side file encryption.
On desktops, the encryption is handled by the service-worker. Since we are not using any server-side processing, the app registers a fake download URL (/file) that is handled by the app service-worker fetch api. this service worker is installed and activated in the browsers once the user visits the site.
