I compiled a list of open-source post-quantum tools and libraries

We recently had to review our cryptographic stack for long-term compliance. We’re not a bank or a government contractor, but we do handle sensitive data that needs to stay secure for 10+ years.

I fell into a rabbit hole of post-quantum cryptography and ended up writing a fairly deep guide. It covers stuff like Kyber, Dilithium, liboqs, PQClean, and hybrid key exchange with OpenSSL.

I tried to keep it practical includes working code examples, trade-offs, and where the standards are headed including the finalized NIST picks. Also added some notes on real-world use cases.

If anyone here is working on something similar or already rolling out PQC in production, would love to hear what libraries or strategies you're using.

Thanks for sharing this—really valuable work! At Quranium, a Layer 1 blockchain protocol optimized for post-quantum security, AI integration, and EVM compatibility, we're working on similar challenges and recently rolled out a post-quantum-ready crypto wallet using SLH-DSA and ML-KEM, both NIST-finalized algorithms. We’ve focused heavily on real-world implementation: integrating split-key architecture for transaction signing and encrypted backups across chains like Bitcoin, Ethereum, and Solana.

Would love to hear how you’ve approached performance trade-offs, especially around key sizes and hybrid models. Also curious if you explored any post-quantum options for recovery flows or user-facing backup systems.

Great to see more people tackling this beyond government or financial sectors.

Could you share it please?

I forgot to mention, I wrote up a full breakdown of the tools I tested Kyber, Dilithium, etc. and how they actually work in practice. Here it is if you’re into that kind of thing: https://ncse.info/post-quantum-tools/

Did you mean to include a link to the list?
