Working on scripts to check PGP signatures of files and faced the problem with gpgv2
$ gpgv2 gpg_test.txt.asc gpg_test.txtgpgv: Signature made Mon 5 Oct 16:35:59 2009 IST using DSA key ID C29DC8ABgpgv: [don't know]: invalid packet (ctb=2d) gpgv: keydb_search failed: Invalid packet gpgv: Can't check signature: No public key
So, it was evident that I'm missing a keyring. How to create one?
Thanks to the clue provided by http://ilostmynotes.blogspot.com/2008/05/debmirror-of-ubuntu-archive-validating.html
So, I listed my keys first:
$ gpg --list-keys Markelov pub 1024D/C29DC8AB 2007-11-13 [expires: 2009-11-12] uid Alex N Markelov (Primary key for emails.) <Alex.Markelov@gmail.com> sub 2048g/E0E8C1F3 2007-11-13 [expires: 2009-11-12]
pub 1024D/55D857AA 2009-02-27 [expires: 2014-02-26] uid Alex Markelov (makeITsimple PGP mail key) <alex@makeitsimple.ie> sub 2048g/EE726DB4 2009-02-27 [expires: 2014-02-26]
pub 1024D/31262C86 2009-02-27 [expires: 2014-02-26] uid Alex N Markelov (markelov.org mail PGP key) <alex@markelov.org> sub 2048g/9C615D16 2009-02-27 [expires: 2014-02-26]
I want the one with ID 0xC29DC8AB:
$ gpg --export 0xC29DC8AB | gpg --no-default-keyring --keyring trustedkeys.gpg --import gpg: keyring `/Users/amarkelo/.gnupg/trustedkeys.gpg' created gpg: key C29DC8AB: public key "Alex N Markelov (Primary key for emails.) <Alex.Markelov@gmail.com>" imported gpg: Total number processed: 1 gpg: imported: 1 gpg: public key of ultimately trusted key 31262C86 not found gpg: public key of ultimately trusted key 55D857AA not found gpg: public key of ultimately trusted key 052A8B73 not found gpg: public key of ultimately trusted key B31ACAE9 not found gpg: 3 marginal(s) needed, 1 complete(s) needed, PGP trust model gpg: depth: 0 valid: 5 signed: 0 trust: 0-, 0q, 0n, 0m, 0f, 5u gpg: next trustdb check due at 2009-11-12
Now gpgv2 is not complaining:
$ gpgv2 gpg_test.txt.asc gpg_test.txt gpgv: Signature made Mon 5 Oct 16:35:59 2009 IST using DSA key ID C29DC8AB gpgv: Good signature from "Alex N Markelov (Primary key for emails.) <Alex.Markelov@gmail.com>"
