Hashing Tools: Hashcat and md5sum

Hashcat is a password recovery tool that uses brute-force and dictionary attacks to crack hashed passwords. While primarily used for penetration testing, it is also valuable for understanding the strength of hashing algorithms.

  • Features:
    • Supports multiple hashing algorithms (MD5, SHA-1, SHA-256, etc.).
    • Highly optimized for performance using GPU acceleration.
  • Hands-On Practice:
    1. Install and set up Hashcat.
    2. Use a dictionary attack to test the strength of a given MD5 hash:
       
      hashcat -m 0 -a 0 hashed_password.txt wordlist.txt

md5sum is a simpler tool for generating MD5 hashes to verify data integrity.

  • Generate an MD5 hash:
     
    md5sum file.txt
  • Verify File Integrity: Compare the generated hash with the expected hash value.
