Hi all,
Hope it’s OK to mention a community fork here, happy for maintainers to remove this if it’s not appropriate.

I can’t speak for the maintainers or the project’s official status, but I’m also a long-time Crypto++ user and rely on it in my own projects.

As a stop-gap for my own needs (newer algorithms), I’ve started maintaining a community fork based on Crypto++ 8.9.0 called cryptopp-modern.

What it currently adds:

• Argon2 password hashing (RFC 9106)
• BLAKE3 cryptographic hash
• Security fixes (Marvin attack CVE-2022-4304, ESIGN improvements)
• Calendar versioning (e.g. 2025.11.0) with more regular releases

Repository: https://github.com/cryptopp-modern/cryptopp-modern

It’s intended to be drop-in compatible with Crypto++ 8.9.0 (same CryptoPP namespace), so it might be helpful for anyone who needs those algorithms or fixes while waiting for an official release.

These changes are also proposed upstream in a series of PRs, so if/when there’s a new official release, I’m keen to align with it and upstream anything that’s useful.

To be clear, upstream Cryptopp is still the authoritative project; cryptopp-modern is just a community-maintained option for specific use cases.
