Assignment Details:
Transposition Cypher:
Explain the logic of the encode/decode scheme of a transposition cipher based on your understanding. Write down the instructions step by step.
The transposition cipher encrypts messages using an even-odd shuffle of characters. To encode a message, it creates two strings. The first string consists of the characters in the message that have an even index. The second string consists of the characters in the message that have an odd index. (This means that if len (message) is odd, then the first “even” string will be longer.) Then the two strings are concatenated (odd characters first) to form the encoded message.
The arguments of both functions are strings, and both functions return strings, encoded or decoded respectively.
This is an example of a transposition cipher:
For example, your output might look like this:
‘If the facts don’t fit the theory, change the facts.’
‘ftefcsdntftteter,cag h at.I h at o’ i h hoy hnetefcs’
‘If the facts don’t fit the theory, change the facts
