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.

- Is this application of AES via cryptoJS secure against common attacks?

How do I encrypt data before sending it to the database?
If you want to encrypt the data on the client, so that no one, not even the server is able to decrypt it, then you could use a javascript client side encryption library like https://github.com/jedisct1/libsodium.js/. In this case the server would see opaque random looking bytea data from the client. Note this means the database can't search within that data, it can only serve the encrypted data back to the client for local decryption.

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).
- Ask HN: What does everyone use for encrypting their personal stuff?
- Intel and AMD CPUs vulnerable to a new speculative execution attack (RETBLEED)

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.
