أداة: MD4 generator
ما الذي يقدمه هذا القسم
MD4 is Rivest's faster follow-up to MD2 and the direct ancestor of MD5. Collisions were demonstrated long ago; Windows LM hashing history involved MD4-era ideas—another reason you should never resurrect it for security decisions.
Why touch it today?
Cryptography coursework, malware archaeology, or verifying antique artifact dumps. Compare digests only inside explicitly labeled labs—never ship new systems depending on MD4.
Tip
If two tools disagree, confirm whether Microsoft-style Unicode buffers versus UTF-8 plain text were hashed.
Password hashing?
Absolutely not—use slow KDFs such as bcrypt or Argon2.
