PGP Keys

I have been using PGP for many years. At first it was just something cool to play with, however I've been building mail servers and computer networks for many years- I know first-hand, exactly how easy it is for ISPs, "hackers", corporations, and governments to read other peoples' email.

And since there is no realistic way to prevent this from happening, it only makes sense to encrypt my emails whenever possible, so that even if they do happen to look at my message (out of the billions of emails which cross the internet every day) they won't be able to read it.

Current key

This is the key I now use on a regular basis:

pub rsa4096/0xA7EC1FBAB3B50007 2017-11-27 [SC] [expires: 2018-11-27] BDC84CA878FD827A4C0BB361A7EC1FBAB3B50007 uid [ full ] John Simpson uid [ full ] John Simpson uid [ full ] John Simpson uid [ full ] John Simpson sub rsa4096/0x2A9EB3A620A1C087 2017-11-27 [E] [expires: 2018-11-27] sub rsa4096/0xCE5735E1E04C1374 2017-11-27 [S] [expires: 2018-11-27] sub rsa4096/0xA634470ECECC41E0 2017-11-27 [A] [expires: 2018-11-27]

This key is also attached to my Keybase account.

Older keys

This key has not been revoked, but I plan on doing so within the next month or so. The key shown above has been signed by this one.

pub rsa4096/0x6B2EDC90B5C6DC30 2017-05-27 [SC] 6353320118E1DEA2F38EAE806B2EDC90B5C6DC30 uid [ultimate] John M. Simpson <> uid [ultimate] John M. Simpson <> sub rsa4096/0x297E5961AB566594 2017-05-27 [E]

This key has not been revoked, but its original expiration date was 2011-08-03. I have updated it to not expire, but not everybody got the update, and some people consider it expired. In the interest of avoiding confusion, and because I wanted a longer key, I have stopped using this key and now use the one above instead.

pub dsa1024/0x8F8D8C9A9014AD1A 2008-08-03 [SC] 5AA49FD4D245733518C2F3D98F8D8C9A9014AD1A uid [ultimate] John M. Simpson <> uid [ultimate] John Simpson <> uid [ultimate] John Simpson <> uid [ultimate] [jpeg image of size 5148] uid [ultimate] John Simpson <> sub elg4096/0xC6655C940F6C5215 2008-08-03 [E]

This was the first key I generated "for real", with the intention of sharing it with the world and using it on a regular basis. I haven't used this one since 1999-2000, and in fact I have forgotten the passphrase for its secret key, so I can't create a revocation certificate for it. Please don't use this key anymore.

pub 1024R/2FB5EDA9 1996-04-06 John Simpson <> Key fingerprint = 8F EA B0 95 6C C4 02 F8 11 1D BE 62 48 09 05 52 uid John Simpson <> uid John Simpson <>

Revoked keys

These are old keys which I have decided I will never use again. If you happen to have one of them in your keyring, please add the revocation certificates as well, so that your PGP client won't try to use them by accident.
