NOTE: For the moment, it appears I once again am able to deal with encrypted email. Please see this page for other secure options for contact.

I used to routinely sign my email messages cryptographically with GnuPG. I no longer do this; in my current social circles, this mostly only causes confusion.
Because GnuPG/PGP signatures are intended to verify that a message actually came from a particular individual, keys are a form of identification. Therefore, in expanding a web of trust, I will only sign keys whose ownership I can verify. That generally means in person with proper identification, however this entails recognition of government authority. So it might also mean, relying just as dubiously on corporate authority, a key posted on a website protected by an SSL certificate which requires identification (class 2 or above). Further information about this can be found on my RetroShare page.
RetroShare and GnuPG users should import the key 0x25E03ED6, preferably from the attachment a the bottom of this page, and confirm that the fingerprint matches the one listed below. FlowCrypt users should match keywords "TUITION CRUISE VANISH ENVELOPE ADVANCE BRACKET." NOTE: I do not currently have RetroShare working as it fails to correctly recognize my existing keys. For further information, see my RetroShare page.
Please note that GnuPG defaults to relatively weak encryption. For stronger encryption, I suggest Robert Hansen's prague tool, which evaluates existing keys. The information on this page also offers useful guidance on how to fix matters with existing keys.

I have attempted to revoke all other keys, but have, in some cases, misplaced the private keys.
In general, mail should be sent to my email@example.com address. However, I also have a gmail address (firstname.lastname@example.org) and a university address (email@example.com). I use the gmail address as a backup for when my mail server is down for any reason, for subscriptions to certain mailing lists that I may be in dire need of should my mail server be down. I rarely send mail from the university address. The gmail address is also an address that I used during a long period when I had no mail server at all.
