OpenSSL Algorithm Bruteforcer

Overview

This script is designed to automate the process of decrypting a file using various OpenSSL encryption modes. It tries to decrypt an input file using a specified password and iterates through a predefined list of OpenSSL modes until it successfully decrypts the file or exhausts all options.

Requirements

• Bash shell (typically available on Unix-based systems)
• OpenSSL installed on your system

Installation

1. Copy the script into a file, e.g., decrypt_script.sh.
2. Make the script executable:

   chmod +x decrypt_script.sh

Usage

Run the script with the password and the input file as arguments:

./decrypt_script.sh [password] [input_file]

• [password]: The password used for decryption.
• [input_file]: The path to the encrypted file.

Modes of Operation

The script includes a wide range of OpenSSL encryption modes, such as AES (various forms), ARIA, Blowfish, Camellia, CAST, DES, RC2, SEED, and SM4.

Limitations & Warnings

• Ensure you have the right to decrypt the file.
• The script does not perform extensive error handling.
• The script stops as soon as it successfully decrypts the file with a mode.
