NTLM Hash Generator
Generate NTLM hashes for Windows authentication testing
- ⚠NTLM is a deprecated authentication protocol with known security vulnerabilities
- ⚠Do NOT use NTLM for production systems - use modern alternatives like Kerberos
- ⚠This tool is for educational and security testing purposes only
Generate NTLM hashes used in legacy Windows authentication systems
NTLM is outdated and vulnerable - included for compatibility and testing only
Outputs hash in uppercase format as used in Windows systems
Enter Password

- Windows Authentication Testing
Test and analyze Windows authentication mechanisms
- Security Testing
Penetration testing and security research on legacy systems
- Digital Forensics
Analyze Windows password hashes in forensic investigations
Algorithm
NTLM uses MD4 hash of UTF-16LE encoded password, which is cryptographically weak
Known Vulnerabilities
NTLM is vulnerable to pass-the-hash attacks, brute-force attacks, and lacks salting
Modern Alternatives
Use Kerberos, bcrypt, Argon2, or other modern authentication mechanisms instead
- •Never use NTLM for new applications or production systems
- •NTLM hashes are relatively easy to crack - use strong passwords if testing
- •This tool is for educational purposes and security testing only
