Reply To: I have not eaten for 48 hours because of 9B – Help!
Speaking from many years’ experience, sleeping, eating, and taking a break to make a sandwich are all incredibly useful tools in your arsenal as a cryptanalyst. The first year I did the cipher challenge I figured out what type of cipher 10B was while cycling back from Thursday evening badminton.
Try to resist the temptation to stare at the ciphertext for hours at a time and you might just be rewarded with an insight while you’re doing the washing up.
