MD4 Hash Generator
Generate legacy MD4 cryptographic hashes instantly. Our free tool processes strings locally, allowing developers to audit vintage systems without uploading sensitive data.
What is the MD4 Generator?
Developed in 1990, MD4 is the predecessor to the famous MD5 algorithm. It was designed to be incredibly fast on 32-bit machines but was quickly proven to be cryptographically insecure due to severe collision vulnerabilities. Today, it is never used for security, but it is still occasionally needed by system administrators auditing legacy NTLM password hashes in very old Windows environments. This utility allows you to instantly generate an MD4 hash from any text string. The algorithm runs entirely client-side, ensuring your plain-text inputs remain strictly confidential.

Frequently Asked Questions
No, MD4 is completely broken and can be cracked almost instantly by modern computers. Use SHA-256 or Bcrypt instead.
Absolutely not. The hashing process happens offline in your browser memory.
No, it is a one-way mathematical function. However, due to its vulnerability, hackers use massive 'rainbow tables' to reverse them quickly.
