Our MD4 Hash Generator provides instant MD4 hash creation from any text input with real-time processing. Simply type or paste your text, and watch as the 32-character MD4 hash is generated immediately. This tool is primarily designed for working with legacy systems that require MD4 hashes, educational purposes, or studying the historical development of cryptographic hash functions.

What makes this tool special is its real-time processing capability combined with additional useful features. As you type, the MD4 hash updates instantly, eliminating the need to click generate buttons repeatedly. The tool also displays character and byte counts for your input, helping you understand exactly what's being hashed. The generated hash is presented in a clean, easy-to-read format with convenient copy functionality.

⚠️ Important Security Notice: MD4 is considered cryptographically broken and should NOT be used for security purposes. It was designed in 1990 and has known vulnerabilities. For secure hashing, please use modern alternatives like SHA-256 or SHA-3. MD4's historical significance lies in its influence on the design of later hash functions like MD5 and the SHA family.

Your privacy is completely protected as all MD4 hash generation happens locally in your browser. Your input text is never sent to any server or stored anywhere. The processing is completely offline, ensuring your sensitive information remains private. The tool works entirely offline once loaded, making it safe for confidential data processing and perfect for environments with restricted internet access.
