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.

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?

CryptoLyzer: A comprehensive cryptographic settings analyzer
It is not just a theory. A special fork of OpenSSL, maintained by Pluralsight author Peter Mosmans, aims to have as many ciphers as possible. This fork is used and recommended by Mozilla Cipherscan, however, it can offer less than two hundred cipher suites, but there are more than three hundred in the different RFCs according to Cipher Suite Info. The majority of them are weak or insecure, which makes it particularly important to be part of the analysis. In addition, it is also true that there are cipher suites that are not on the Cipher Suite Info list, for instance, Russian standard (GOST) cipher suites. These are rarely used cipher suites, but there is an OpenSSL engine that implements them, so they should be checked.
What are some alternatives?
sslyze - Fast and powerful SSL/TLS scanning library.
http-observatory - Mozilla HTTP Observatory
OpenSSL - TLS/SSL and crypto library
testssl.sh - Testing TLS/SSL encryption anywhere on any port
wolfssl - The wolfSSL library is a small, fast, portable implementation of TLS/SSL for embedded devices to the cloud. wolfSSL supports up to TLS 1.3!
ssldump - ssldump - (de-facto repository gathering patches around the cyberspace)
openssl - 'Extra featured' OpenSSL with ChaCha20 and Poly1305 support
cipherscan - A very simple way to find out which SSL ciphersuites are supported by a target.
openssl - Fork of OpenSSL 1.1.1 that includes prototype quantum-resistant algorithms and ciphersuites based on liboqs [OQS-OpenSSL 1.1.1 is NO LONGER SUPPORTED, please switch to OQS-Provider for OpenSSL 3]
