# Deranged Alphabet Generator

## Answers to Questions (FAQ)

### What is a deranged alphabet? (Definition)

A deranged alphabet (disordered) is a mixture of the 26 letters in an order different from the traditional alphabetical order (A,B,C,…) creating a new arrangement.

Example: ZYXWVUTSRQPONMLKJIHGFEDCBA is a disordered alphabet, it contains the 26 letters but it is not the order ABCDEFGHIJKLMNOPQRSTUVWXYZ

### What is a random alphabet?

Definition: A random alphabet has 26 letters in a totally randomized manner without following a particular order (shuffle often difficult to memorize).

### What is a reciprocal alphabet?

A reciprocal (or reversible) alphabet is a cipher alphabet where each letter is paired with another unique letter, creating a two-way correspondence. So if a plain letter A is crypted by X, then the plain letter X is crypted A.

Example: DCOEABFGHIJKLMNPQRSTUVWXYZ is a reciprocal alphabet, DCODE is encrypted as MNPMQ and MNPMQ is encrypted as DCODE

### What is an inverse/reciprocal alphabet?

During a mono-alphabetic substitution, a disturbed alphabet makes it possible to carry out a ciphering by substitution.

The reverse alphabet is the disturbed alphabet that it allows to find the original message.

Example: For the alphabet QWERTYUIOPASDFGHJKLZXCVBNM, the reverse alphabet is KXVMCNOPHQRSZYIJADLEGWBUFT.

To generate the reverse alphabet:

— for each letter i of the normal alphabet, note its position j in the disturbed alphabet, and write in the reverse alphabet the letter in position j in the normal alphabet.

Example: A is the 1st letter of the alphabet, A is in position 11 in the deranged alphabet QWERTYUIOPASDFGHJKLZXCVBNM, so the 1st letter of the reverse alphabet is the 11th letter of the normal alphabet: K

### What is an alphanumeric alphabet?

An alphanumeric alphabet has 36 characters: 26 letters and 10 digits.

Example: ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789

### Why use a key to generate an alphabet?

Using a key helps to scramble the letters in the alphabet with a single keyword to remember

Example: DCOEABFGHIJKLMNPQRSTUVWXYZ is a deranged alphabet generated with key DCODE.

### What are the most frequent deranged alphabets?

QWERTYUIOPASDFGHJKLZXCVBNM : QWERTY keyboard

MNBVCXZLKJHGFDSAPOIUYTREWQ : reverse QWERTY keyboard

AZERTYUIOPQSDFGHJKLMWXCVBN : AZERTY keyboard

NBVCXWMLKJHGFDSQPOIUYTREZA : reverse AZERTY keyboard

ZYXWVUTSRQPONMLKJIHGFEDCBA : reverse alphabet

AEIOUYBCDFGHJKLMNPQRSTVWXZ : vowels then consonants

### How to use a deranged alphabet to cipher a message?

Choose a method for encryption that accepts a deranged alphabet. dCode has many choices for that, select the right of yours, by default, use mono-alphabetic substitution.

### What is the algorithm to generate a disordered alphabet?

A random disordered alphabet can be created by reversing the positions of the letters (Fisher-Yates shuffle):`function randomAlphabet() { alphabet = "ABCDEFGHIJKLMNOPQRSTUVWXYZ" derangedAlphabet = alphabet for (i = 25 ; i > 0 ; i--) { index = rand(0, i) swap( derangedAlphabet[i], derangedAlphabet[randomIndex] ) } return derangedAlphabet}`

The rand(a,b) function picks a random number between a and b

The swap(a,b) function swaps the values of a and b
