Security Tools
MD5 Generator
Compute an MD5 hash of any text using a hand-rolled in-browser implementation. The output is a 32-character lowercase hex string. MD5 is cryptographically broken — use it only for non-security checksums.
This is a sensitive tool. Your input is processed locally and never leaves your device — not even temporarily.

How to use
- 1
Enter your text
Type or paste up to 1 MB of text. Use “Load sample” to try a known input whose MD5 you can verify.
- 2
Compute the hash
Click “Compute MD5”. The hand-rolled in-browser MD5 implementation runs entirely on your device — no external library, no network call.
- 3
Copy the result
The 32-character lowercase hex digest appears below the input. Use Copy to put it on your clipboard.
Common use cases
- Match a legacy MD5 checksum published alongside an old download.
- Generate a quick fingerprint for deduplicating short strings.
- Reproduce an MD5 value needed by an integration that has not migrated to SHA-256 yet.
- Teach how MD5 works without installing a library.
Limitations
- MD5 is cryptographically broken — collisions can be computed in seconds. Never use it for security.
- Inputs larger than 1 MB are rejected to keep the page responsive.
- This tool only computes plain MD5, not HMAC-MD5 or salted variants.
- Do not store password hashes as MD5 — use bcrypt, scrypt or Argon2 instead.
