When hobbies come together, nice things happen. Back in the end of 2020 I decided to move this blog. At the time I thought the free Oracle cloud tier would be inadequate for any serious work. Oh boy was I wrong!!!
If you're developing for the web (or something else) and you need to connect to an Oracle database, such as an Oracle Autonomous Database that comes for free with oracle cloud free tier, you may run to the typical problem of storing db connection credentials in configuration files and scripts. Nevertheless, Oracle has, since ages, a functionality called Oracle Wallet that can help you manage these connections more securely. Keep in mind that Oracle migrates away from Wallets, but my understanding is that this is a response to usability concerns, as the security standard is not maintained in the new set-up.
I decided to move this blog to Oracle Cloud. I am very satisfied wth my current hosting provider and I plan to maintain my VPS there, but I also have good reasons to move.
As you may have heard, Let's Encrypt revoked several certificates today that were issued through a faulty process. Read on for the details, and on how to identify the revoked certificates themselves.
