MD2 & MD4 Generators

Created on 9 November, 2025 • Generator Tools • 0 views

Generate legacy MD2 and MD4 digests only when required by old systems. Prefer modern hashes for any security-sensitive task.

What They Are

MD2 and MD4 are early hash functions now considered cryptographically broken. They remain only for backward compatibility with very old protocols or archives.

Use With Caution

Step-by-Step

1. Paste data or upload the legacy file.
2. Compute MD2 or MD4 digest.
3. Record that the algorithm is legacy in your notes.

Safer Alternatives

1. For integrity: SHA-256 or SHA-3 family.
2. For passwords: bcrypt, scrypt, or Argon2id.

Risk Notes

Be Aware

1. Collisions are practical.
2. Never design new systems on MD2/MD4/MD5.
