In JavaScript, you can use ternary operations to implement basic data encryption and decryption. Ternary operations offer a concise way to conditionally assign values based on a given condition.

Encryption Process

To encrypt data using ternary operations, you can follow these steps:

1. Convert the message into an array of characters.
2. Iterate over each character in the array.
3. Use a ternary operation to encrypt each character by converting it to its corresponding ASCII value and adding an offset value.
4. Store the encrypted characters in a new array.
5. Join the encrypted characters into a string and return the encrypted message.

Here’s an example implementation:

function encrypt(message, offset) {
  const encryptedChars = message.split("").map(char => {
    const encryptedCharCode = (char.charCodeAt(0) + offset) % 256;
    return String.fromCharCode(encryptedCharCode);
  });
  return encryptedChars.join("");
}

const encryptedMessage = encrypt("Hello, World!", 5);
console.log(encryptedMessage); // Displays "Mjqqt,#%Twyj@"

In the above example, we encrypt the message “Hello, World!” by shifting each character’s ASCII code by an offset value of 5.

Decryption Process

To decrypt the encrypted message, we can perform the inverse operation using ternary operations as well:

1. Convert the encrypted message into an array of characters.
2. Iterate over each character in the array.
3. Use a ternary operation to decrypt each character by subtracting the offset value and converting it back to its corresponding ASCII value.
4. Store the decrypted characters in a new array.
5. Join the decrypted characters into a string and return the decrypted message.

Here’s an example implementation:

function decrypt(encryptedMessage, offset) {
  const decryptedChars = encryptedMessage.split("").map(char => {
    const decryptedCharCode = (char.charCodeAt(0) - offset + 256) % 256;
    return String.fromCharCode(decryptedCharCode);
  });
  return decryptedChars.join("");
}

const decryptedMessage = decrypt("Mjqqt,#%Twyj@", 5);
console.log(decryptedMessage); // Displays "Hello, World!"

In this example, we decrypt the message “Mjqqt,#%Twyj@” by shifting each character’s ASCII code back by the offset value of 5.

Conclusion

Using ternary operations, you can implement a simple encryption and decryption process in JavaScript. While this approach is not suitable for highly secure encryption, it can be useful for basic data obfuscation or when used in conjunction with stronger encryption algorithms.
