Encrypt - File Encryption and Decryption

Description

Encrypt is a Python-based tool that allows you to encrypt and decrypt files in your current directory. Using the cryptography.fernet library, it ensures secure encryption with generated keys, making it suitable for protecting sensitive files. The script also provides the ability to rename files with a prefix (e.g., locked-) after encryption.

Features

• File Encryption: Encrypts all files (except specified ones) in the current directory.
• File Decryption: Decrypts previously encrypted files.
• Key Management: Automatically generates and saves a key for encryption and decryption.

Prerequisites

• Python 3.6 or later
• cryptography library (install it using pip install cryptography)

Usage

1. Clone or download the repository containing the script.
2. Ensure all files you want to encrypt or decrypt are in the same directory as the script.
3. Run the script and follow the prompts.

Command-line Options

• Encrypt Files

  1. Choose option 1 when prompted.
  2. Confirm the operation by entering Y or y.
  3. All eligible files will be encrypted and renamed with the locked- prefix.

• Decrypt Files

  1. Choose option 2 when prompted.
  2. The script will attempt to decrypt all encrypted files.

Key File

• A key file (key.txt) will be generated during the first run.
• Ensure the key.txt file remains in the directory; it is required for decrypting files.

Example

python cryptog.py

# Output:
# Şifrelemek   (encrypt) [1]
# Şifre Çözmek (decrypt) [2]
# :

Encryption Example:

Şifrelemek   (encrypt) [1] 
Gerçekten şifrelemek istiyor musunuz? [Y] 

# Output:
# Şifrelendi

Decryption Example:

Şifre Çözmek (decrypt) [2] 

# Output:
# Şifre Çözüldü.

Files Ignored by the Script

The following files are not encrypted or decrypted:

• cryptog.py
