Encryption and Decryption in Python Using OOP

class Encrypt:
    def __init__(self):
        self.send = ""
        self.res = []

    # Sender encrypts the data
    def sender(self):
        self.send = input("Enter the data: ")
        self.res = [ord(i) + 2 for i in self.send]  
        print("Encrypted data:", "".join(chr(i) for i in self.res))

class Decrypt(Encrypt):
    # Receiver decrypts the data
    def receiver(self):
        decrypted_data = "".join(chr(i - 2) for i in self.res)  
        print("Decrypted data:", decrypted_data)

# Usage
obj = Decrypt()
obj.sender()
obj.receiver()

Explanation:

Class Encrypt:

• __init__: Initializes with original_data to store the user's input and encrypted_data to store the encrypted result.
• encrypt: Takes user input, encrypts it by adding 2 to each character's ASCII value, and stores the encrypted values.

Class Decrypt:

• Inherits from Encrypt.
• decrypt: Decrypts the encrypted_data by subtracting 2 from each ASCII value, recovering the original text.

Workflow:

• The Encrypt class encrypts the input text.
• The Decrypt class decrypts the encrypted text to recover the original data.
