Keyboard Code

- Substitution Cipher

Keyboard Code, also known as Keyboard Cipher or Keyboard Encryption, is a simple and straightforward method of encrypting and decrypting messages using a keyboard layout as a reference. It is a type of substitution cipher, where each letter of the plaintext is replaced with a corresponding letter from the keyboard layout.

To use Keyboard Code, one needs a standard QWERTY keyboard or any other specific keyboard layout. The encryption process involves finding the position of each letter in the plaintext on the keyboard and replacing it with the corresponding letter located at the same position on the keyboard.

For example, if the letter "A" is in the top-left corner of the keyboard, it will be replaced with another letter, let's say "F," which is also in the top-left corner. The same applies to other letters according to their respective positions on the keyboard.

Decryption follows the reverse process, where the ciphertext letters are matched with their corresponding positions on the keyboard to reveal the original message.

Keyboard Code is relatively easy to use and doesn't require complex algorithms. However, it is considered a weak encryption method, as it can be easily deciphered through simple analysis or known patterns in the language. Therefore, it is not suitable for protecting sensitive or valuable information but can serve as a fun and educational tool for encoding messages in informal settings.
