Answers to Questions (FAQ)
How to encrypt using Nomenclature cipher?
Nomenclator encryption uses a substitution of letters by words or words by letters or even groups of words.
It is possible to transform any word into a sentence and any sentence into word or letter. It all depends on the nomenclature used.
A classic idea is to replace each letter with a word that begins with the same letter (it is possible to try to make a sentence).

How to decrypt Nomenclature cipher?
Nomenclator decryption requires knowing the nomenclature used (dictionary/alphabet/correlation table) and search and replace content.
How to recognize Nomenclature ciphertext?
The message does not have any characteristic and if the encoding is done right it can be perfectly intelligible.
However, in the event that a letter is replaced by a unique word, the message may comprise several repeated words.
How to decipher Nomenclature without Nomenclature?
It is impossible except in special cases.
In the case a letter is replaced by a single word, then replace each word with a random letter and perform attack using frequency analysis.
In the case where each letter has been replaced by a word beginning with the given letter, then replace each word with its first letter.
