A key-signing event is a get together with GnuPG/PGP users for the purpose of meeting other GnuPG/PGP users and signing each other's keys. This extends the Web of Trust that GnuPG/PGP relies upon. At the OSHCA2007 conference there will be an official key-signing event for all who send their info in advance. If you show up at OSHCA2007 with your key information and ID, but did not send in the information beforehand, we will have a separate, one on one, key verification session. Anyone and everyone is invited. We sign keys because GnuPG/PGP is based upon a Web of Trust. This web of trust is what ensures that no one can pretend to be you and that you can really believe that a message you receive from Dr. Jones is really from Dr. Jones. The more deep and tightly inter-linked the web of trust is, the more difficult it is to defeat.
