MD5 for quick checksums — not for storing passwords
Paste text; get 32-hex MD5. State clearly: MD5 is broken for collision resistance; fine for non-security checksums and legacy APIs.
chars: 10
When to use
Matching a published checksum or talking to an old API that still wants MD5 — not for password storage.
Examples
How it works
Pure JS MD5 (or equivalent) over UTF-8 bytes → hex. MD5 is broken for collision resistance.
Common pitfalls
- Not for passwords or integrity against attackers.
- Encoding (UTF-8 vs UTF-16) changes the digest.
- Prefer SHA-256 for new designs.
How this differs
MD5 for legacy checks; SHA-1 similarly legacy; SHA-256 for stronger checksums. Still not encryption.
FAQ
Safe for passwords?
**No.** Use a password hasher (bcrypt/scrypt/argon2) server-side.
File MD5?
Text first; file hashing optional later.
Uppercase hex?
