    I made a bit of a cypherpunk experiment - PHP textboard forum script that
    uses PGP for authorization of posting messages (messages must be PGP
    signed to pass). It also requires Argon2 PoW to register a key with the
    forum as a kind of an anti-spam measure.
    https://codeberg.org/grgmusk/mmmb
    To post messages a user has to
    1. Register theirs PGP key (there's a link in page top) by submitting
    public PGP key and Argon2 hash of it's fingerprint calculated with
    forum's required parameters (they're on the registration page,
    configurable in forum settings)
    ( echo -n ABCD1FGHIJA2CDEFG3IJABC4EFGH6JABC8EFGHIJ|argon2 sOmEsAlT123 -t
    60 -k 471040 -p 1)
    2. Sign a message with that PGP key, put it into form in New thread/Reply
    link.

    I'm not even sure if it all works as intended lol.
    I'll try running a live demo at

    shortly after sending this news article. It won't run long, maybe for a
    day. Please try posting something.
