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?

Dovecot not offering TLSv1.2 after a few minutes
The current configuration allows for TLSv1 to TLSv1.3 connections. I can verify those using testssl.sh, the tests will succeed (although correctly mentioning, that TLSv1 and TLSv1.1 should be disabled). Running the tests again after about 5 minutes, the results are different. TLSv1.2 now shows "not offered and downgraded to a weaker protocol".
