Top 10 most intriguing Java errors in 2024
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 :)

YYYY? yyyy!
Firstly, I took a look at GitHub. What if it really was a bug, the developers had already found it and committed a fix? That's exactly what happened. Here's a link to the commit, you can check it out. All of our 'Y' (week year) characters in the pattern were replaced with 'y' (year).

Show HN: filippo.io/mlkem768 – Post-Quantum Cryptography for the Go Ecosystem
Note that there may be incompatibilities until NIST has published the final revisions. Some specifications are on Round 3 kyber, others are on FIPS 203.
This one will interoperate with Bouncy Castle as we both use FIPS 203 draft, but won't interoperate with OQS that is still on the Round 3 submission.

Java implementation of a quantum computing resistant cryptographic algorithm
The readme mentions a dependency on Bouncy Castle - note that BC already contains several Java-based PQC signature schemes, see https://doc.primekey.com/bouncycastle/interoperability#Inter... and https://github.com/bcgit/bc-java

Help with BouncyCastle OpenPGP (Java)
The best official resources are probably the example classes in the bouncycastle repository. They give you a rough idea for how to use the API, although they are a bit minimal unfortunately. You can probably apply a lot of domain knowledge (what algorithms are good/bad) from openpgpjs too, although you'd have to find out how the respective method calls are called on the BC side.
