Clever. We did something similar for a friend getting married. Instead of giving his present directly we created a text file encrypted with his public pgp key. We printed out the ascii-armored cryptotext and handed it over. He had lots of fun typing it back into his computer.
Anyway, as he decided to give the SSL key, pulling this kind of prank seems bit childish. On the other hand, he must have been under a heavy pressure, so can't blame the guy for not thinking 100% straight.
Sad, that people are sidetracked to talking about the font size instead of warrantless wiretapping.
