This project has three source files, namely MessageEncryptor.java, Message.java and

SecureMessagesFrame.java.

The MessageEncryptor class has a method to encrypt a message using the encryption technique of WeDoSecureApps.

The Message class simply represents a message

The SecureMessageF anonymous classes.

The Caesar Cipher is a basic encryption technique named after Julius Caesar, who

reportedly used it to protect his private messages. It involves shifting the letters the alphabet by a fixed number of places. Here's a step$-$by$-$step explanation:

Step $1$: Understand the Alphabet Shift

In the Caesar Cipher, each letter in the plaintext $($the original message$)$ is replaced by

of $3$: $-\text{'}$A$\text{'}$ beco

$\text{'}$A$\text{'}$ becomes $\text{'}$D$\text{'}$

$\text{'}$C$\text{'}$ becomes $\text{'}F\text{'}$

Step $2$: Choose a Shift Value

The shift value determines how many positions each letter is moved. The team uses a shift value of $3$

Step $3$: Encrypt the Message

To encrypt a message, replace each letter in the plaintext with the letter that is the

specified number of positions down the alphabet. If the end of the alphabet is

reached, wrap around to the beginning.

Example: $-$ Plaintext: "HELLO" Shift: $3$

Shift: $3$

$-...,$ and so on

Step $2$: Choose a Shift Value

The shift value shift value of $3$

Step $3$: Encrypt the Messag

reached, wrap around to the beginning.

Example:

Plaintext: "HELLO" $-$ Shift: $3$

$\text{'}{H}^{\text{'}}->\text{'}$ C

$\text{'}$E$\text{'}->\text{'}$H

$\text{'}$L$\text{'}->\text{'}$O$\text{'}$

Encrypted message $($ciphertext$)$: "KHOOR

Step $4$: Consider Case and Non$-$Letter Characters

"Case Sensitivity"$*$: Usually, the Caesar Cipher ignores the case of letters. However,

${?}^{**}$ Non$-$Letter maintain the case if desired.

encrypted and remain unchanged.
