SafeCrypt

A Python-based utility tool for secure encryption and file management.

Overview

This Python script provides functionality to encrypt and decrypt:

• Messages
• Files
• Directories

using Fernet symmetric encryption from the Cryptography library.

It also provides functionality to shred files and directories.

Features

• Encrypt/Decrypt text messages.
• Encrypt/Decrypt individual files.
• Encrypt/Decrypt all the files in a directory.
• Shred a file/directories so that it can't be recovered.
• Option to generate new encryption keys or load existing ones.
• Simple Command-line-interface.
• ANSI color-coded terminal output for better UX.
• Warning for existing files before overwriting them.
• Optional output files for encrypted/decrypted files.
• Log information about encrypted/decrypted files and directories
• Error handling and user friedly prompts.

Requirements

To use this script you will need these installed on your system:

• Python 3.x
• cryptography Library for encryption and decryption.

Usage

Running the script:

Please use a terminal which can show colors as they can typically support ANSI escape codes

git clone https://github.com/LilSuperUser/SafeCrypt
cd SafeCrypt
pip install -r requirements.txt
chmod +x ./safecrypt.py
python ./safecrypt.py

Menu options:

1. Encrypt a message: Enter a message and the script will encrypt it using loaded/generated key.

2. Encrypt a file: Provide the name of the file/path to the file to encrypt it in place/save to a new file.

3. Encrypt a directory: Provide the path to a directory and all files within it will be encrypted but Sub-directories will be skipped.

4. Decrypt a message: Enter an encrypted message and the script will decrypt it using the key you provide.

5. Decrypt a file: Provide the name of the file/path to the file to decrypt it in place/save to a new file.

6. Decrypt a directory: Provide the path to an encrypted directory and all files within it will be decrypted.

7. Shred a file: Shred a file ==> Delete a file such that it can't be recovered.

8. Shred a directory: Shred all files and sub directories present in a directory.

Key management:

The script currently provides the following key management options:

• Generate a new key: Generates a new key and saves it to a file of user's choice.
• Load an existing key: Loads an existing eky from a file fo user's choice.

Important: Make sure to store your keys securely, as losing them will make it impossible to decrypt your encrypted messages or files.

Planned Features

• Add a GUI.
• Progress bar for directory encryption/decryption.
• Multi-threaded file processing for faster encryption/decryption.
• Password-based encryption (PBKDF2).
• Compression of files before encryption.
• File integrity verification using hash checks.
