-The master branch of **pqm4** contains schemes that either [selected for standardization by NIST](https://csrc.nist.gov/Projects/post-quantum-cryptography/selected-algorithms-2022),
-part of the [4th round of the NIST PQC standardization process](https://csrc.nist.gov/Projects/post-quantum-cryptography/round-4-submissions),
-or part or the [first round of additional signatures of the NIST PQC standardization process](https://csrc.nist.gov/projects/pqc-dig-sig/round-1-additional-signatures).
