Generally true. But suppose I'm in an internet cafe, reading El Reg, and posting an encrypted message (see below) using El Reg, directed to my secret buddy. I'm just wondering a few things:
1. Does logging help anyone find out WHO I AM?
2. Does logging help anyone identify my buddy?
3. Can anyone read my book cipher message?
4. And supposing I'm a VERY BAD PERSON...can any of the above be done in time to make any difference?
