2002 August 16, Tom Wilson, “Disabling keycatching apps on cafe machines”, in alt.cybercafes (Usenet)I've been using PGPv8 for a while with a DH/DSS key-pair. I've recently got hold of an Aladdin eToken, which integrates with PGP and allows me to generate a RSA key-pair on the token itself. I like the idea of offloading the private key as it effectively gets round the issue of a keycatcher obtaining my PGP passphrase (obviously they could still capture my token passcode, but without the token it wouldn't be much use).
