Transposition ciphers transposition ciphers as their name suggests, in transposition ciphers, the letters of the message to be encoded -what cryptographers call the ‘plaintext’ - are simply rearranged (or ‘transposed’) forming an anagram . A transposition cipher is one which rearranges the order of the letters in the ciphertext (encoded text), according to some predetermined method, without making any substitutions suppose we want to encrypt the following message, a quote from 'peter rabbit' by beatrix potter: now run along and don't get into mischief, i'm going out.
