GnuPG https://gnupg.org/ Content Credentials in ProofMode https://proofmode.org/verify.html change the game from centralized X.509 certificates to utilizing OpenPGP and https://opentimestamps.org OTS.

Here is the C2PA specification. Let’s continue to decentralize proof of personhood! 🤳🔏🚥🛜

Thank you for bringing this concept to Nostr.

We have been working with GnuPGP on keygrips computed internally as a hash over the canonical S‑expression of the public key parameters for ISO-7816 NFC cards in NeoPGP via JCOP. These would work as good notary keys for decentralized privacy based OTS attestations.

GnuPG KeyGrips! 🔑🔑🔑
