What are Javascript Key Codes? (Definition)
The JavaScript (JS) language associates with each key of the keyboard a numerical code named keycode. Here is the complete table:
| 8 | [BACKSPACE ⌫] | 9 | [TAB ↹] | 13 | [ENTER ⏎] | 16 | [SHIFT ⇧] |
|---|---|---|---|---|---|---|---|
| 17 | [CTRL] | 18 | [ALT] | 19 | [PAUSE] | 20 | [CAPS LOCK 🔒] |

| 220 | \ | 221 | ) | 222 | ' |
Uppercase letters and numbers have the same codes as the ASCII code.
How to encrypt using Javascript Key Codes cipher?
Any series of keyboard keys (and therefore letters) can be encoded with numbers (the keycodes).
Example: JAVA is coded 74,65,86,65
How to decrypt Javascript key codes cipher?
Each code corresponds to a key, decryption is therefore a substitution of numbers by the corresponding key.
Example: '83,67,82,73,80,84 decrypts SCRIPT'
How to recognize a Javascript Key Codes ciphertext?
The letters are encoded by numbers between 65 and 90 (as ASCII code).
In a JavaScript code, the use of the keyboard keys is generally related to a key-typed event (keyDown or keyUp event) the presence of these keywords is a clue.
How to simulate keyboard key presses in JavaScript?
For obvious security reasons, it is impossible to type keyboard keys from Javascript.
