Now that you are talking about security, it reminds me that few months
ago it has been noted on Debian mailing list that Debian maintainers
should use 2048 or 4096-bit gpg keys and they consider 1024-bit keys
to be bruteforceable.
(http://article.gmane.org/gmane.linux.debian.devel.project/22458).

Trinity QuickBuild repository key is only 1024-bit rsa
(1024R/2B8638D0). Same for the QuickBuild axis key (1024R/80479E11).
