  • Checking PGP/GnuPG Signatures in tin

    From Russell@21:1/5 to All on Sat May 22 13:50:59 2021
    I see a lot of people signing their posts with PGP and GnuPG, but when I
    view the post, I just see the signature as an attachment. I can view the attachments with 'V' and open the signature block, but I can't figure
    out how to check the validity of the signed message. I've added the
    public key to my gpg keyring and tried several variations of a mailcap
    entry, but nothing works. Tin hooks the line in mailcap, but I get an
    error that the command failed. I think I'm on the right track, but I
    can't figure out the details since tin doesn't have a lot of
    documentation.

    Anyway, do any of you have this working in tin? How?

    inline pgp/gpg (none mime) should work via ^G when viewing an article
    (and pgp/gpg was propperly detected/configured at compile time).

    when mime is involved 'V' and mailcap should work

    this is from my ~/.mailcap which I havn't touched for ages, can't say if
    that still works, I don't do gpg.

    application/pgp-signature;\
    NAME=%s \&\& DATA=`echo $NAME|sed 's,\\(unknown-00.\\)\\.pgp,\\1.asc,'|tr '123456789' '012345678'` \&\& gpg --verify %s $DATA; needsterminal

    and for headersigning (like in control messages) '|'"pgpverify" should do
    it.

    That didn't work. I guess it just can't be done. At least I don't
    understand enough to get it to work. I almost never see anyone using
    inline signatures and I don't know that I've ever seen header signing.
    If the developer of tin doesn't have it working, I guess it just doesn't
    work. I'm not really a programmer or I'd look into it, but I wouldn't
    even know where to start.

    Thank you for your suggestions. Please followup if you figure it out.
    I'll do the same if I stumble onto a solution. lol!

    well, I don't do gpg, so that's _low_ on the list.
    the note about RFC 2015 in TODO is ~20 years old.

    as a last resort you could either pipe '|' the article to metamutt from the pager (that's what I would do; I have metamail_prog left blank so tin does
    the (other) mime handling internally).

    a copy of metamutt (which of course requires a propperly configured mutt)
    comes with the tin source, upstream is <https://www.spinnaker.de/mutt/metamutt>.

    or set metamail_prog (from 'M'enu / tinrc) to metamutt (I don't like that
    (at least not without ask_for_metamail=ON), but YMMV).
