Requirement already satisfied: pyfiglet in /usr/lib/python3/dist-packages (0.8.post0)īuilding wheels for collected packages: rarfile, py-termīuilding wheel for rarfile (setup.py). We also need to install some dependencies for Zydra to work properly - it uses Python 3, so we can use pip3 to install the extra modules: ~$ pip3 install rarfile pyfiglet py-term If you're lazy like me, it's just one less key to press: ~$ mv Zydra.py zydra.py Next, and this step is completely optional, let's rename the script making it entirely lowercase. To begin, we need to download Zydra from GitHub - use the wget utility to grab the Python file right from the command line: ~$ wget Encryption algorithms used for these can vary depending on the system, but MD5, SHA-512, SHA-256, Blowfish, and DES are all commonly used. Linux shadow files themselves are not encrypted, but the passwords contained within them are. Other methods to create PDF files include Microsoft Office and Adobe Acrobat - Office versions 2007+ and Acrobat versions 7+ all support AES encryption. Older versions of LibreOffice use the Blowfish algorithm to encrypt files, but versions 3.5 and up use AES.

If you're using Linux, it's easy to create PDFs in LibreOffice by exporting regular word documents, and there's even an option to password protect the newly created file. Don't Miss: Crack Shadow Hashes After Getting Root on a Linux System.WinRAR and PeaZip, popular choices that can deal with RAR files, also use the AES standard. Earlier versions of the RAR protocol use a proprietary encryption algorithm, while newer versions use AES. Other programs, like WinZip and 7-Zip, use strong AES-256 encryption. How Are These Files Encrypted?ĭepending on the program used and its version, these sorts of files could be password protected using various encryption algorithms.įor example, the Linux command line zip utility uses the older PKZIP algorithm, which is insecure and easy to crack.

That's where Zydra comes in - a tool for cracking RAR files, ZIP files, PDF files, and Linux shadow files. Sometimes, even certain files that are encrypted aren't safe from attackers. Everybody knows not to store sensitive information in unencrypted files, right? PDFs and ZIP files can often contain a treasure trove of information, such as network diagrams, IP addresses, and login credentials.
