Cifra de César for PC

The Caesar Cipher is a basic encryption method created by Julius Caesar to communicate between his generals.

The method consists of exchanging the letters of the original message for another letter of the alphabet and moving it by a certain number of positions, to the right or left. Considering only alphabetic characters, upper or lower case.

Accents, numbers or any other special characters will be disregarded. If you use accented vowels or c cedilha (ç), both will be replaced by their unaccented equivalents.

This number of displacements is the key to encrypting and deciphering the text. The key number can vary from 1 to 25, as there are only 26 letters in the alphabet.

So, if, for example, we use the key 3, each letter will be replaced by the 3rd letter to its right, considering its position in the alphabet. That is, the letter "A" will be replaced by the letter "D". To decipher, just do the reverse process.

However, the Caesar Cipher demonstrates safe decline, as it is easily broken. Therefore, the Caesar Cipher is not suitable for protecting more sensitive information, although it is useful for teaching purposes due to its simplicity.
