Pat's GPG key

Long ago, I had a series of PGP keys on all the keyservers. They had any of a number of email names, including pfarrell@cybercash.com and pfarrell@cs.gmu.edu. These keys started from October 1992 and PGP version 2.A typical one was 8E6FF28D Fingerprint = 1593 763F 3C62 1EB4 6F71 ACB1 E15A 66C1

But I have long since changed computer too many times, and used PGP too infrequently to keep the private keyring handy. So lets call those keys lost. Plus, PGP version 2 keys are way old, and those were too small.

PGP has been replaced in the open source world by GPG.

Here is my GPG key. Here it is directly for all (with good eyesight or use Ctrl-+ to increase the size in your browser) to see:
