Banks and 128 bit DES

Just got done giving a two-day primer on PKI. First morning was "what is
crypto". First afternoon was "what is key management". I use a lot of
"Radio Orphan Annie Secret Decoder Badges" (ROASDBs) - Original Enigma is
6, DES is 16, Skipjack is 32, 3Des is 48. Also use "cost to break" figures
- U$250 for 40 bit, U$5,000 for 56 bit. It makes sense to non math majors 8*).
