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.

> I have no room for TLS on micro computer
How micro is your micro? There are embedded TLS stacks such as wolfSSL[1]. If you carefully select the cipher suite and certificate requirements, and perhaps limit TLS payload sizes, you may be able to fit on a lot more systems than you initially suspect. x.509 is expensive in code space though, if that's the constraint, you may do better with an application specific certificate replacement of some sort.

CryptoLyzer: A comprehensive cryptographic settings analyzer
There are many notable open-source projects (SSLyze, CipherScan, testssl.sh, tls-scan, …) and several SaaS solutions (CryptCheck, CypherCraft, Hardenize, ImmuniWeb, Mozilla Observatory, SSL Labs, …) to do a security setting analysis, especially when we are talking about TLS, which is the most common and popular cryptographic protocol. However, most of these tools heavily depend on one or more versions of one or more cryptographic protocol libraries, like GnuTLS, OpenSSL, or wolfSSL. But why is this such a problem?

OpenWrt 23.05
It's work in progress: https://github.com/Mbed-TLS/mbedtls/blob/development/docs/ar...
Newer version have okay-ish support, I'd guess the next OpenWRT release will have it again.

How can I disable the close_notify message?
It's related to this Mbed-TLS issue

DIY Physical Backed Tokens (EIP-5791) with ESP32 and BLE
i've used the entropy generator from MbedTLS which uses multiple sources of randomness, and seeding it additionally with the chip's mac address and the free heap size at time of creation. it would take a lot to recreate all that "noise" consistently, but i'm open to suggestions on how to make it more secure

Help libraries won’t work on the IDE for esp32
However on the github page and assuming I found the right source - and this is a HUGE ASSUMPTION - there is a section on porting the library to other platforms.

redbean: a single-file actually portable web server with Lua, HTTPS and SQLite
Rebean is a single executable written in ANSI C that embeds Lua 5.4, MbedTLS and SQLite. The crazy thing about this is that it is a C binary that runs on six operating systems without any cross compiling thanks to leveraging Justine Tunney's cosmopolitan.

Install mbedTLS on Linux
it looks like the commands are all built under https://github.com/Mbed-TLS/mbedtls/tree/development/programs and the arch mbedtls package does some extra work to rename them and copy them into /usr/local/bin: https://github.com/archlinux/svntogit-community/blob/packages/mbedtls/trunk/PKGBUILD#L55

Elliptic Curve Cryptography Explained
If you want to see a real implemention of arbitrary sized integer math, mbedTLS is a great example:
https://github.com/ARMmbed/mbedtls/blob/development/library/...
All of the ECC code in that library relies on this code, which can be accelerated by dedicated hardware.

WireGuard implementation for LwIP stack
Definitely, FreeRTOS + LwIP + Mbed TLS is a fairly common combo these days, and Mbed TLS has hardware acceleration where possible.
