Due to the specifics of the week number, so testing isn't the best pal to find this error. So why does such a topical bug come in the last place? The reason is that the warning isn't from the actual version of Bouncy Castle but from our testing base. The old sources still remain there, and this bug has been fixed for a long time. This is such a salute from the past, just a time travel again :)

Project mention: What Okta Bcrypt incident can teach us about designing better APIs | dev.to | 2025-01-22I decided to check other Google results, and the next Java library in the list was bcrypt from Patrick Favre (link to GitHub repo) with 513 starts and the last release version 0.10.2 (so, not stable) from 12th of February 2023 (almost 2 years old). This suggested that I'd not use it in production, but why not to run our tests.
