How Are These Files Encrypted?

Bajirao mastani serial episode 14. Depending on the program used and its version, these sorts of files could be password protected using various encryption algorithms.

For example, the Linux command line zip utility uses the older PKZIP algorithm, which is insecure and easy to crack. Other programs, like WinZip and 7-Zip, use strong AES-256 encryption. Earlier versions of the RAR protocol use a proprietary encryption algorithm, while newer versions use AES. WinRAR and PeaZip, popular choices that can deal with RAR files, also use the AES standard.

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. Older versions of LibreOffice use the Blowfish algorithm to encrypt files, but versions 3.5 and up use AES. Other methods to create PDF files include Microsoft Office and Adobe Acrobat — Office versions 2007+ and Acrobat versions 7+ all support AES encryption.

Linux shadow files themselves are not encrypted, but the passwords contained within them are. Encryption algorithms used for these can vary depending on the system, but MD5, SHA-512, SHA-256, Blowfish, and DES are all commonly used.

This tutorial demonstrates how to crack passwords on encrypted ZIP files. The application used for this example is fcrackzip.

Software

• fcrackzip

Install fcrackzip

• Included in Kali Linux
• If not currently installed on your distro:
  • $sudo apt-get update
  • $sudo apt-get install fcrackzip

Using fcrackzip

For this example, we will use a dictionary attack to crack a ZIP password. Start by creating a text file and storing it in an encrypted ZIP file.

• $cat > file.txt
• $This is a sample file. (Press enter)
• Ctrl + C
• $cat file.txt
• $zip –encrypt sample.zip file.txt
• Repeat password twice

Kavremvr exe. To view options for fcrackzip, use the following command (manpage found here):

• $fcrackzip –help

Use the rockyou.txt word list that comes default with Kali. Sudo is required to move this file.

• $sudo cp /usr/share/wordlists/rockyou.txt.gz rockyou.txt.gz
• $sudo gzip -d rockyou.txt.gz

Use fcrackzip and rockyou.txt to crack the password on the ZIP file. Adjust the paths for your environment.

• $fcrackzip -v -u -D -p /home/pentaroot/rockyou.txt /home/pentaroot/sample.zip
  • -u(–use-unzip); helps with false positives
  • -D (–dictionary); selects dictionary mode
  • -p (–init-password string); use to select the rockyou.txt file
  • -v (–verbose); not required

Fcrackzip found the password ‘starwars’. If this did not work for your password, you may try additional word lists found on Kali or download additional ones online to try.

There are other ways to use fcrackzip to crack ZIP passwords rather than using a dictionary attack. Brute forcing is another option that is worth a try. Start with an easy password for a dictionary attack and then move on to a brute force attack with a stronger password. As mentioned previously, refer to the fcrackzip man page for additional options.
