TLS Check for github.com

Why Check TLS for github.com?

TLS (Transport Layer Security) encrypts data in transit between your browser and github.com. Older protocols like TLS 1.0 and 1.1 have known vulnerabilities and are deprecated by major browsers. Our TLS checker tests which protocol versions github.com supports, identifies the preferred cipher suites, and assigns a security grade. Ensuring github.com supports TLS 1.2 or 1.3 is critical for protecting user data and maintaining compliance with modern security standards like PCI DSS.
