File Encryption and Decryption Module 📁🔐

[bhargavnova]

Objective:

Write a Python module that enables users to easily encrypt and decrypt files. This functionality will enhance the security of sensitive data stored in files.

Features:

1. Encryption Functionality:

   • Create a function that can encrypt a given file using a secure encryption algorithm.

2. Decryption Functionality:

   • Implement a function that can decrypt an encrypted file, restoring it to its original state.

3. Password Protection:

   • Allow users to set and use a password for encryption and decryption operations.

4. Robust Error Handling:

   • Implement thorough error handling to gracefully manage edge cases and invalid inputs.

Example Usage:

import file_encryptor

# Encrypt a file
file_encryptor.encrypt_file("/path/to/input_file.txt", "/path/to/output_file.enc", "my_password")

# Decrypt a file
file_encryptor.decrypt_file("/path/to/encrypted_file.enc", "/path/to/decrypted_output.txt", "my_password")

Difficulty: Beginner/Intermediate Tags: Python, Encryption

Note: The main point of this module is to implement encryption and decryption functionality to files, no matter what approach you follow.

Hello @bhargavnova , I would like to contribute to this, I have been into Python and Django dev for quite some time and would love to test my skillset in developing this.

[bhargavnova]

Sure!! Just a little advice, it's better to use Python instead of Django, it should be a fair and simple script, and Django is quite a robust framework.

Happy coding!! :)

[SaranshBaniyal]

Yeah sure thing @bhargavnova , there is no point in using Django here, when all u need is a simple python module. Thanks for assigning the issue😁

@bhargavnova I have one doubt, do we have to generate the .enc file for encryption, as I am able to overwrite the file with encrypted data and then upon entering the key/password the file gets overwritten with decrypted data

[bhargavnova]

Yes if we use a single script, that will overwrite the data,

so I think you should follow this approach,

ask for the password, if the file exists without .enc, then encrypt the file and make .enc file, the old file will be removed,

If the .enc file exists, then the script will try to decrypt that file, using password provided by the user,

Hope this helps, Fill free to ask any doubts you have. @SaranshBaniyal

In short every time scripts gets run, it will ask for the password from the user, and depending on which file exists, script will know what whether perform decryption or encryption
