> 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.

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