Equivalent segments between different Fedora & RPM Fusion ASCII armored key blocks

[wavelength]

Can someone explain why large segments within the ASCII armored key blocks of
Fedora 11 & 12 match? Attached below are the respective key blocks. Two
matching regions between the blocks are highlighted with bold arrows.

In addition, large segments within the
RPM-GPG-KEY-rpmfusion-free-fedora-12-primary key match parts of these same
segments (highlighted in italics - see below). I assume this is normal, but
it's unclear why this would be the case.

Also, what do the last 8 digits signify in the output below?

rpm -qa gpg-pubkey*

gpg-pubkey-16ca1a56-4a100959
gpg-pubkey-57bbccba-4a6f97af

Thanks in advance
