At the moment, I'm trying to check the fingerprint of the oracle_vbox.asc key that I downloaded from http://www.virtualbox.org/wiki/Linux_Downloads: they provide the key and the fingerprint but no instructions for reviewing this information myself.



How do I show the fingerprint of the key I just downloaded?



apt-key finger oracle_vbox.asc shows the fingerprints of all trusted keys, which isn't what I want.

Get the key:



$ wget http://download.virtualbox.org/virtualbox/debian/oracle_vbox.asc


Print the key fingerprint with GPG version 1:



$ gpg --with-fingerprint oracle_vbox.asc 
pub 1024D/98AB5139 2010-05-18 Oracle Corporation
(VirtualBox archive signing key) <[email protected]>
Key fingerprint = 7B0F AB3A 13B9 0743 5925 D9C9 5442 2A4B 98AB 5139
sub 2048g/281DDC4B 2010-05-18
Key fingerprint = 27B0 97CF 8257 4209 C434 8D42 B674 8A65 281D DC4B


Note that the 2nd fingeprint is just the fingerprint of the sub-key.



Print the fingerprint with GPG version 2:



$ gpg2 -n -q --import --import-options import-show  oracle_vbox.asc   
pub dsa1024 2010-05-18 [SC]
7B0FAB3A13B907435925D9C954422A4B98AB5139
uid Oracle Corporation (VirtualBox archive signing key) <[email protected]>
sub elg2048 2010-05-18 [E]


Note that -n is an alias for --dry-run, i.e. the key isn't actually imported.



Alternatively, to just display the fingerprints:



$ gpg2 -nq --import --import-options import-show --with-colons oracle_vbox.asc 
| awk -F: '$1 == "fpr" { print $10 }'
