Encryptions
Just one question - where do you start with caches that are based on encrypted clues?
I know we have a few experts around here (no, not looking at you Dodo, honest  ) but for the uninitiated where do you start? do you need special software and how do you learn these things?
Curious and stuck.... Sian

Absolutely no software OR computers needed! Encryptions were meant not to be capable of being read unless the sender and the recipient BOTH know the
secret of that particular message system. (Watched the BBC Sherlock recently?) The best place to start is with history books.

Agreed, buite force, no matter how cleaver is very hit and miss.
I built a program to bruit force Dodo's D5 and it found a few possibilities but with each extra letter on the keyword tried it takes exponentially
extra time.
So a 5 letter code word = 5min, 6 = 30min, 7 = 3.5hrs, 8 = about a day, 9=over a week etc.......
I think i may have to buy a certain book :-p
