 ### Post-quantum cryptography in OpenPGP
 
-There is [ongoing work](https://datatracker.ietf.org/doc/draft-wussler-openpgp-pqc/) to standardize and add support for post-quantum {term}`public-key algorithms<Public Key Algorithm>` in OpenPGP. This project is funded by the [german "BSI"](https://en.wikipedia.org/wiki/Federal_Office_for_Information_Security). Goals include adding support for post-quantum cryptography to Thunderbird and GnuPG. A [presentation](https://datatracker.ietf.org/meeting/113/materials/slides-113-openpgp-a-post-quantum-approach-for-openpgp-00) was given at [IETF 113](https://datatracker.ietf.org/meeting/113/session/openpgp/).
