Changelog

2024-10-24

  • pqcrypto-kyber and pqcrypto-dilithium are retired and replaced by pqcrypto-mlkem and pqcrypto-mldsa, respectively.
  • pqcrypto-falcon now separates Falcon into the "compressed" mode and the "padded" variants. The "compressed" variant likely produces shorter signatures than the max size.

2024-01-25

  • Update Kyber clean implementation to avoid potential Kyber side-channel vulnerabilities. Note that the aarch64 implementation is still vulnerable, but it is waiting for other updates. This library is for experimental purposes, so security vulnerabilties are addressed on a best-effort basis.
