Here's your chance to crack ciphers similar to those Bletchley Park's codebreakers faced during World War II. Below, we present three ciphers of different levels of difficulty, from easiest to ...

The two applications may use the same key for each of the two steps ... H E R S M E L T O F E L D E R B E R R I E S Then read the cipher off by columns, starting with the lowest-numbered column ...
