GitHub recently updated its SSL setup to enhance security by introducing support for Forward Secrecy and Authenticated Encryption Ciphers, which offer stronger protection against attacks. Forward Secrecy ensures that even if encryption keys are compromised, past communication remains secure, while Authenticated Encryption provides ciphers less susceptible to vulnerabilities. The updates are already supported by browsers like Chrome, and additional information about the setup can be found on SSL Labs. For those interested in a deeper dive into these changes, a more detailed post has been published by Dirkjan Bussink.
