mhi has asked for the wisdom of the Perl Monks concerning the following question:
Fellow Monks!
In trying to verify a PGP signature and determine the Key ID of the signing key, I have been stumped by the strange format I encountered in reading out that Key ID.
Expecting to find it in the usual hex format, I instead was offered 'key_id' => 'yp▒▒▒▒▒'. To me this is especially confusing as accoring to the docs when creating a signature, you are supposed to enter the Key-ID as an 8- or 16-digit hex number.
Here's a code snippet:
use Crypt::OpenPGP; ... my $pgp = Crypt::OpenPGP->new; my($userid,$sigobj) = $pgp->verify( Signature => $mailbody, Data => $mailbody, ); unless(defined $userid){ done(1,"Could not verify signature."); } printf("KeyID: 0x%x\nUserID:%s\n",$sigobj->key_id, $userid);
Output:
Argument "ypM-&M-^W^]M-^UM-\rM-^W" isn't numeric in printf at ./script.pl line 118. KeyID: 0x0 UserID:Test Key <testkey@example.com>
How can I get the Key-ID in hex? Am I just not seeing it? I would be delighted to be enlightened. :-)
Update/Correction: Input of course would be an 8- or 16-digit hex no., not 10 as I previously wrote.
