Documentation 📖

> Caesar Cipher:

The Caesar Cipher is a substitution cipher used in cryptography that shifts the alphabet by a fixed number of positions. It is one of the simplest and most widely known encryption techniques.

caesarCipher (text: string, shift: number = 3): string

Encrypts a message using the Caesar cipher.

• text: The message to be encrypted.
• shift: The number of positions to shift the alphabet. Default is 3.

caesarDecipher (text: string, shift: number = 3): string

Decrypts a message using the Caesar cipher.

• text: The message to be decrypted.
• shift: The number of positions to shift the alphabet. Default is 3.

Note

During encryption using the caesarCipher function, characters not part of the Latin alphabet, such as uppercase letters, accented characters, non-alphanumeric characters, or numbers, will be ignored and will retain their original form.
