To handle encryption and decryption exceptions and failures in python, deploy a try-except block to catch exceptions such as “valueError” or “CipherError”.

Each character in the input string is shifted forward by one position, making the text unreadable to anyone without the decryption key. Usage. Run the script enc.py. Enter the text you wish to encrypt ...

Symmetric encryption uses the same key for both encryption and decryption, making it straightforward for securing data. In Python, the cryptography library's Fernet class helps implement this.

To run the RSA key generation, encryption, and decryption program, follow these steps: Save the Python code for RSA key generation, encryption, and decryption in a file named rsa_program.py. Make sure ...
