For as long as humans have tried to send secret messages, cryptography has been around to make sure the messages stay secretive. Cryptography is defined as the art of writing and solving codes. There are two parts of this process, encryption, which is writing secret codes, and decryption, which is solving the codes. Cryptography is one of the most important things in computing and is vital to make sure things are safe and secure. Without cryptography, technology would be very different. Early ciphers were called classical ciphers. They used paper and writing utensils and sometimes mechanical things to aid in encryption and decryption. Early ciphers were mostly used for war secrets. They made it so if the enemy intercepted your message likely by killing the guy with the note, they would not be able to decipher it because they don’t know how to read the cipher and it would have no impact for you losing the secret. Most classical ciphers are easy to crack. Some of them can just be cracked using just a brute force attack. This is just trying every possible combination of ciphers to decrypt a message. Others can be broken this way, but it is much harder because there are more possible combinations so it will take longer. Cryptography has been around for a very long time. One of the first ciphers was the Caesar Cipher. This cipher has been around for thousands of years. It is named after Julius Caesar, the famous Roman emperor, who used it to communicate with his generals in…
