MD4 Hash Generator — Fast 128-bit Hash Function

Create MD4 cryptographic hashes online from any text input. MD4 is a legacy message-digest algorithm producing a 128-bit hash value, designed by Ron Rivest as a precursor to MD5. Although MD4 has known cryptographic vulnerabilities and should not be used for security-sensitive applications, it is the basis for NTLM authentication in Windows systems.

MD4 Hash Generation Applications

• Windows NTLM authentication hash analysis and research
• Legacy protocol compatibility testing
• Forensic analysis of older authentication systems
• Educational comparison with MD5 and MD2 algorithms
• Security research and vulnerability analysis

MD4 was foundational in the development of modern hash algorithms and is still encountered in Windows network authentication contexts. Security professionals use MD4 hash analysis for penetration testing and forensic investigations of legacy Windows environments. For secure applications, always use SHA-256, SHA-3, or bcrypt.
