In cryptography, a key signing party is an event at which people present their PGP-compatible keys to others in person, who, if they are confident the key actually belongs to the person who claims it, digitally signs the PGP certificate containing that public key and the person's name, etc. This is one way to strengthen the web of trust. Although PGP keys are generally used with personal computers for Internet-related applications, key signing parties themselves generally don't involve computers, since that would give adversaries increased opportunities for subterfuge.
