filesecure 0.7.0

A file encryption and decryption tool

FileSecure Tool

FileSecure is a command-line utility for encrypting and decrypting files using AES-256-CBC encryption. This tool allows you to securely protect your files with a password, ensuring that sensitive data is not exposed.

Features

• Encrypt Files: Secure your files with AES-256-CBC encryption.
• Decrypt Files: Restore encrypted files back to their original state.
• Easy to Use: Simple command-line interface with straightforward commands.
• Password-Based Encryption: Utilize a password to derive a strong encryption key.

Installation

To use the FileSecure tool, you need to have Python and pip installed on your system.

pip install filesecure

Usage

Encrypting a File

To encrypt a file, use the following command:

filesecure encrypt --password "your_password" yourfile.txt --output-file yourfile.txt.secured

Parameters

• --password "your_password": The password used to encrypt the file. Make sure to use a strong password.
• yourfile.txt: The name of the file you want to encrypt.
• --output-file "yourfile.txt.secured" (optional): The name of the file where the encrypted content will be saved. If not provided, the original file will be overwritten.

Important Notes

• If --output-file is not provided, the original file will be overwritten with the encrypted content.
• If the file is already encrypted (i.e., it starts with FILE_SECURE), a message will indicate that the file is already encrypted.

Decrypting a File

To decrypt a file, use the following command:

filesecure decrypt --password "your_password" yourfile.txt.secured --output-file yourfile.txt

Parameters

• --password "your_password": The password used to decrypt the file. It must match the password used during encryption.
• yourfile.txt.secured: The name of the file you want to decrypt.
• --output-file "yourfile.txt" (optional): The name of the file where the decrypted content will be saved. If not provided, the original file will be overwritten.

Important Notes

• If --output-file is not provided, the original file will be overwritten with the decrypted content.
• If the file is not encrypted (i.e., it does not start with FILE_SECURE), an error message will indicate that the file is not encrypted or is in an invalid format.
