Stephen Lombardo OpenPGP Key Transition.txt
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512
Date: April 23rd, 2014
For a number of reasons, I've recently set up a new OpenPGP key,
and will be transitioning away from my old one.
The old key will continue to be valid for some time, but I prefer all
future correspondence to come to the new one. I would also like this
new key to be re-integrated into the web of trust. This message is
signed by both keys to certify the transition.
The old key was:
pub 4096R/0x7CA502E93DB91BD9 2011-04-18
Key fingerprint = C55C 52E1 723D 166A BD1F 64F1 7CA5 02E9 3DB9 1BD9
And the new key is:
pub 4096R/0x52E8883F1591F4CE 2014-04-22 [expires: 2017-04-21]
Key fingerprint = D922 0490 1CD8 BFDF 63A2 D9F9 52E8 883F 1591 F4CE
To fetch the full key from a public key server, you can simply do:
gpg --keyserver hkps.pool.sks-keyservers.net --recv-key '0x52E8883F1591F4CE'
If you already know my old key, you can now verify that the new key is
signed by the old one:
gpg --check-sigs 'D92204901CD8BFDF63A2D9F952E8883F1591F4CE'
If you don't already know my old key, or you just want to be double
extra paranoid, you can check the fingerprint against the one above:
gpg --fingerprint 'D92204901CD8BFDF63A2D9F952E8883F1591F4CE'
If you are satisfied that you've got the right key, and the UIDs match
what you expect, I'd appreciate it if you would sign my key. You can
do that by issuing the following command:
**
NOTE: if you have previously signed my key but did a local-only
signature (lsign), you will not want to issue the following, instead
you will want to use --lsign-key, and not send the signatures to the
keyserver
**
gpg --sign-key 'D92204901CD8BFDF63A2D9F952E8883F1591F4CE'
I'd like to receive your signatures on my key. You can either send me
an e-mail with the new signatures (if you have a functional MTA on
your system):
gpg --export 'D92204901CD8BFDF63A2D9F952E8883F1591F4CE' | \
gpg --encrypt -r 'D92204901CD8BFDF63A2D9F952E8883F1591F4CE' --armor | \
mail -s 'OpenPGP Signatures' <[email protected]>
Additionally, I highly recommend that you implement a mechanism to keep your key
material up-to-date so that you obtain the latest revocations, and other updates
in a timely manner. You can do regular key updates by using parcimonie[0] to
refresh your keyring. Parcimonie is a daemon that slowly refreshes your keyring
from a keyserver over Tor. It uses a randomized sleep, and fresh tor circuits
for each key. The purpose is to make it hard for an attacker to correlate the
key updates with your keyring.
I also highly recommend checking out the excellent Riseup GPG best
practices doc, from which I stole most of the text for this transition
message ;-)

Please let me know if you have any questions, or problems, and sorry
for the inconvenience.
