  • How does one create a digital sig to sign a post?

    From Fritz Wuehler@fritz@spamexpire-202510.rodent.frell.theremailer.net to alt.privacy.anon-server,alt.privacy on Sunday, October 12, 2025 18:54:19

    A PGP public sig is much too large to use.

    Sample of what I see signing a usenet post.

    This signature probably requires that you need the public
    key to verify it.

    Another approach with larger signatures is using yubicrypt,
    which embedds the key in the signature, so that you don't
    have to collect the keys and additionally yubicrypt shows
    you an identicon, so that you know those come from your
    friends. Thus allowing you anonymous signatures, when not
    giving away the public key.

    If your PGP key is the newer type ECC (Elliptic-curve cryptography)
    you will notice the signature blurb is much smaller in size than
    that generated by the older RSA keys. See this signature.

    But far more important than the size of a signature
    is to provider your recipient with a way to verify it.
    A PGP sgnature can only be verified if the author's
    PGP public key is made available for the reader.

    Mine can be downloaded here: <https://keys.openpgp.org/vks/v1/by-fingerprint/0564484C8A2E3DBAEB0DBE85C94D423355A83863>

    But unfortunately this does not prove that they
    key belongs to a person who claims it belongs to
    him, if not publicity signed by third parties.

    My yubicrypt certificates, for example, are eIDAS
    certified, so that the whole world knows the keys
    belong to me. An advantage IMHO the old PGP WoT
    does not have.
