What is Ophcrack?

Ophcrack is a powerful tool used for cracking Windows passwords. It is based on Rainbow Tables, which are precomputed tables used to crack password hashes.

Features of Ophcrack

Ophcrack offers several features that make it a popular choice for password cracking:

1. Cracks LM and NTLM Windows hashes

Ophcrack is capable of cracking both LM and NTLM hashes used by Windows operating systems. This means it can crack passwords for Windows XP, Vista, and 7.

2. Free tables available for Windows XP, Vista, and 7

Ophcrack provides free tables specifically designed for Windows XP, Vista, and 7. These tables contain precomputed password hashes, making the cracking process faster and more efficient.

3. Brute-force module for simple passwords

In addition to Rainbow Tables, Ophcrack also includes a brute-force module. This module is useful for cracking simple passwords that may not be present in the Rainbow Tables.

4. Audit mode and CSV export

Ophcrack offers an audit mode that allows users to analyze the strength of their passwords. It also provides the option to export the results in CSV format for further analysis.

5. Real-time graphs to analyze the passwords

To aid in password analysis, Ophcrack provides real-time graphs that visually represent the strength of passwords. These graphs can help users identify patterns and make informed decisions about password security.

6. LiveCD available to simplify the cracking

Ophcrack offers a LiveCD version, which is a bootable CD or USB drive that allows users to run Ophcrack without installing it on their system. This simplifies the cracking process and makes it more accessible to users.

7. Loads hashes from encrypted SAM recovered from a Windows partition

Ophcrack can load password hashes from an encrypted Security Account Manager (SAM) file recovered from a Windows partition. This means it can crack passwords even if the original Windows installation is not accessible.

In conclusion, Ophcrack is a versatile and powerful tool for cracking Windows passwords. Its features, such as support for LM and NTLM hashes, free tables for specific Windows versions, brute-force module, audit mode, real-time graphs, LiveCD option, and ability to load hashes from encrypted SAM files, make it an essential tool for password recovery and security analysis.
