Keyboard Change Cipher

Keyboard change encryption consists of substituting two different keyboard layouts. Computer keyboards have a number of key and a similar layout/shape, the typing of the 2nd key of the 2nd row will not necessarily give the same letter on a US keyboard (QWERTY) or an European keyboard (AZERTY).

Select the 2 types of keyboard to swap

The letter in Q position on a QWERTY keyboard is the letter A on the AZERTY keyboard or P on a DVORAK keyboard.

The encryption and decryption are identical. Superimpose the keyboard mentally or use the substitution table.

The QWERTY and AZERTY keyboards (most commonly used) have several common pairs (location, letter) such as the letters ERTYUIOPSDFGHJKL

Logically, your operating system can handle all the keyboards layouts. The keys send a code and this code can be interpreted as any character or letter.

On Windows, the key combination ALT + SHIFT or WINDOWS + SPACE allows you to change keyboard settings.

Physically, all keyboards are compatible (USB standard).

The message is a mono-alphabetic substitution, no change in index of coincidence.

For a case change the symbols become numbers and vice versa.

For a passage from AZERTY to QWERTY, the accents become numbers.

There are many variations in the position of the keys on a keyboard depending on the country. It is also possible to agree on a given keyboard keys' shift.
