NIST PQC Final Standards

[p-barabas]

Hi,

on 13.Aug. 2024 NIST has published final PQC standard ( FIPS 203-205):
https://csrc.nist.gov/publications/fips

Is it planned to update Botan library with differences and to be able to use algorithms by defined standards?

Thanks in advance for your response.

Yes! We're on it in context of the BSI Project 481:

• PQC: ML-KEM #3893
• PQC: ML-DSA #4270
• PQC: SLH-DSA #4291

Currently these open pull requests contain implementations of the IPD-versions but they'll be updated (and hopefully merged) before the next planned release in October.

Thank you.

The mentioned algorithm implementations are now merged and slated for release in Botan 3.6.0 next week. The signature algorithms ML-DSA and SLH-DSA won't support the pre-hash mode and will lack support for the application-defined "context" string. Those features will be implemented in a later release.
