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.

Backstage: cryptographic R&D internship at Cossack Labs
Now, the real world work starts. We introduce interns to the world of popular cryptographic libraries, help them to make their first OSS contributions, and let them practice with our cryptographic library Themis which provides a high-level crypto API on 14 languages.

Libsodium: A modern, portable, easy to use crypto library
Libsodium has been around for a while, so probably the reason it was posted is that version 1.0.19 was just released: https://github.com/jedisct1/libsodium/releases/tag/1.0.19-RE...
Updated NuGet and Swift packages are going to be uploaded soon.
AEGIS-128X and 256X are not there yet, but if you need them, they are available in libaegis: https://github.com/jedisct1/libaegis
All the code from libaegis will eventually be merged into libsodium, including the incremental update API which is especially useful for TLS.

I created an encrypted command line jounal
To address both of these vulnerabilities, you should instead use a library that handles these sharp edges for you. A well received library in the security and cryptography communities is libsodium. It has high level functions that handle password hashing and data encryption for you, reducing the risk that you introduce vulnerabilities in your code, such as you have here.

Dangerous toys: Anything to ed25519 (SSH Keys)
This article [0] has a good explanation of why clamping is necessary. But the process is very simple, you just generate 256 random bits, clear the three lowest order to avoid small subgroup attacks, then clear the highest order and set the second highest order to avoid side-channel attacks which may occur if an implementation isn’t constant-time. The Libsodium source shows this pretty clearly: [1], lines 18-23.

monero-python 0.99 is released, testers welcome!
Finally I managed to replace the slow pure-Python reference implementation of Ed25519 cryptography with pynacl which is a binding to libsodium, the industry standard lightning-fast C library.
What are some alternatives?
OpenSSL - TLS/SSL and crypto library
Crypto++ - free C++ class library of cryptographic schemes
mbedTLS - An open source, portable, easy to use, readable and flexible TLS library, and reference implementation of the PSA Cryptography API. Releases are on a varying cadence, typically around 3 - 6 months between releases.
libhydrogen - A lightweight, secure, easy-to-use crypto library suitable for constrained environments.
Botan - Cryptography Toolkit
Bcrypt - Modern(-ish) password hashing for your software and your servers
DOMPurify - DOMPurify - a DOM-only, super-fast, uber-tolerant XSS sanitizer for HTML, MathML and SVG. DOMPurify works with a secure default, but offers a lot of configurability and hooks. Demo:
LibTomCrypt - LibTomCrypt is a fairly comprehensive, modular and portable cryptographic toolkit that provides developers with a vast array of well known published block ciphers, one-way hash functions, chaining modes, pseudo-random number generators, public key cryptography and a plethora of other routines.
tweetnacl-java - TweetNaCl in Java - a port of TweetNaCl-js
LibreSSL - LibreSSL Portable itself. This includes the build scaffold and compatibility layer that builds portable LibreSSL from the OpenBSD source code. Pull requests or patches sent to [email protected] are welcome.
cryptography - cryptography is a package designed to expose cryptographic primitives and recipes to Python developers.
