Dear #Letsencrypt, you helped secure millions and millions of servers, not just web servers. But your announcement at letsencrypt.org/2025/05/14/end… about ending Ending TLS Client Authentication Certificate Support in 2026 because Google changes their requirements would result in your certificates becoming a possible risk for ensuring SMTP traffic. Please think again. Please.

Ending TLS Client Authentication Certificate Support in 2026
Let’s Encrypt will no longer include the “TLS Client Authentication” Extended Key Usage (EKU) in our certificates beginning in 2026. Most users who use Let’s Encrypt to secure websites won’t be affected and won’t need to take any action.letsencrypt.org

Love that attitude!
Great writeup and reminder about how easy it is to be tricked by the simple stuff. Using homoglyphs like these is relatively common in phishing emails, but we may not bee good enough at looking for them elsewhere.

When I suggested to my colleague to press backspace and press the minus key he was dumbstruck that git detected a file change.
