Try out the new experience. Alphabetical substitution cipher: Encode and decode online. A monoalphabetical substitution cipher uses a fixed substitution over the entire message. The ciphertext alphabet may be a shifted, reversed, mixed or ... Each column of this table forms a dictionary of symbols representing the alphabet: thus, in the A column, the symbol is the same as the letter represented; in the B column, A is represented by B, B by C, and so on. To use the table, some word or sentence should be agreed on by two correspondents. This may be called the 'key-word', or 'key-sentence', and should be carried in the memory only. how do telescopes help us
