What this skill does
Hashcat Password Recovery Overview Hashcat is the world's fastest password recovery tool, supporting over 300 hash algorithms and multiple attack modes. This skill covers authorized password auditing, forensic password recovery, and security research applications. IMPORTANT: Password cracking must only be performed on hashes you are authorized to crack. Unauthorized password cracking is illegal. Always ensure proper authorization and legal compliance. Quick Start Basic password cracking: Core Workflow Password Cracking Workflow Progress: [ ] 1. Verify authorization for password cracking [ ] 2. Identify hash algorithm type [ ] 3. Prepare hash file and wordlists [ ] 4. Select appropriate attack mode [ ] 5. Execute cracking operation [ ] 6. Analyze cracked passwords [ ] 7. Document password policy weaknesses [ ] 8. Securely delete hash files and results Work through each step systematically. Check off completed items. 1. Authorization Verification CRITICAL: Before any password cracking: Confirm written authorization from data owner Verify legal right to crack captured hashes Understand data handling and retention requirements Document chain of custody for forensic cases Ensure secure storage of cracked passwords 2. Hash Identification Identify hash algorithm: 3. Hash File Preparation Prepare hash files: 4. Attack Modes Choose appropriate attack mode: Dictionary Attack (Mode 0): Combinator Attack (Mode 1): Brute-Force Attack (Mode 3): Mask Attack (Mode 3 with patterns): Hybrid Attacks (Modes 6 & 7): Character Sets: ?l = lowercase (abcdefghijklmnopqrstuvwxyz) ?u = uppercase (ABCDEFGHIJKLMNOPQRSTUVWXYZ) ?d = digits (0123456789) ?s = special characters (!@#$%^&...) ?a = all characters (l+u+d+s) ?b = all printable ASCII 5. Performance Optimization Optimize cracking performance: 6. Rules and Mutations Apply password mutation rules: 7. Session Management Manage cracking sessions: 8. …
