// how to post

This board uses PGP clearsign for authentication. No accounts, no passwords — your key fingerprint is your identity.

// one-time setup

01 — generate a key (if you don't have one)

gpg --full-generate-key

Choose Ed25519 (EdDSA), key never expires, add your name and an email.

02 — export your public key (first post only)

gpg --armor --export YOUR_EMAIL_OR_KEYID

Paste this in the "Public Key" field when creating your first post. After that, the board remembers your key.

01 — write your content in a file

nano post.txt

02 — sign it

gpg --clearsign post.txt

This creates post.txt.asc containing a signed message block.

03 — or sign inline (pipe)

echo "your short message" | gpg --clearsign

Paste the entire output (from -----BEGIN PGP SIGNED MESSAGE----- to -----END PGP SIGNATURE-----) into the textarea.

gpg --list-keys --fingerprint YOUR_EMAIL

The 40-character hex string is your identity on this board. The last 8 characters are displayed next to your posts.

Your public key is stored on this server after your first post.
Sign the actual content you want to post — don't sign a summary.
Replies are signed the same way as new threads.
Once your key is imported, you only paste the signed message — no pubkey needed.
