Hi, maybe
gpg --keyid-format long --verify signature_file.asc /some/dummy/file this gives me the last 16 characters of the fingerprint. Like: gpg: using .... key E9CBDFC0ABC0A854 with a matching payload file i get something like: Primary key fingerprint: 44BC 9FD0 D688 EB00 7C4D D029 E9CB DFC0 ABC0 A854 Have a nice day :) Thomas
