   Anchor Relay – A faster, easier way to get Let's Encrypt certificates▲80

   From the cryptic terminal commands to the innumerable ways to shoot yourself in the foot, I always struggled to use TLS certificates. I love how much easier (and cheaper) Let's Encrypt made it to get certificates, but there are still plenty of things to struggle with. That's why we built Relay: a free, browser-based tool that streamlines the ACME workflow, especially for tricky setups like homelabs. Relay acts as a secure intermediary between your ACME client and public certificate authorities like Let's Encrypt. Some ways Relay provides a better experience: - really fast, streamlined…

    PGT-Proxy – A PostgreSQL Proxy in 277 Lines of Rust▲10

    It's time we talked about something many developers, data analysts, and even web application servers are guilty of: downgrading PostgreSQL connection security. Too often, we see connections dropped from full TLS verification to "any TLS" (i.e., sslmode=require) or, even worse, plain text connections. Why? Because most cloud providers, like AWS or Google Cloud SQL, use non-public Certificate Authorities for PostgreSQL. The result?
