The PQClean project is being\narchived in or after July 2026 (see [PQClean/PQClean#604](https://github.com/PQClean/PQClean/issues/604)),\nafter which no further security patches or bug fixes will be applied to the\nupstream implementations.\n\nAs a result, this crate will no longer receive updates. Users should migrate\nto the [`fn-dsa`](https://crates.io/crates/fn-dsa) crate, which provides a\npure-Rust implementation of FN-DSA (FIPS 206).","modified":"2026-06-04T15:00:04.609886025Z","published":"2026-06-04T12:00:00Z","database_specific":{"license":"CC0-1.0"},"references":[{"type":"PACKAGE","url":"https://crates.io/crates/pqcrypto-falcon"},{"type":"ADVISORY","url":"https://rustsec.org/advisories/RUSTSEC-2026-0165.html"},{"type":"REPORT","url":"https://github.com/rustpq/pqcrypto/issues/97"}],"affected":[{"package":{"name":"pqcrypto-falcon","ecosystem":"crates.io","purl":"pkg:cargo/pqcrypto-falcon"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0.0.0-0"}]}],"ecosystem_specific":{"affects":{"functions":[],"arch":[],"os":[]},"affected_functions":null},"database_specific":{"source":"https://github.com/rustsec/advisory-db/blob/osv/crates/RUSTSEC-2026-0165.json","informational":"unmaintained","categories":[],"cvss":null}}],"schema_version":"1.7.5"}
