MD5 Generator
Generate an MD5 hash for non-security checksums. 100% client-side — never use MD5 for passwords or signatures.
What is MD5 — and what is it safe for?
MD5 (Message Digest 5, designed by Ron Rivest in 1991) produces a 128-bit fingerprint and was once the most widely deployed hash function on the internet. It is now CRYPTOGRAPHICALLY BROKEN: practical collision attacks have existed since 2004, and chosen-prefix collisions since 2008. MD5 must NEVER be used for passwords, digital signatures, certificates, HMAC keys, or anything an attacker could exploit. The only legitimate remaining uses are non-adversarial integrity checks: verifying a file downloaded without accidental corruption, deduplication, cache keys, or quick fingerprints inside a trusted system. For anything security-relevant, use SHA-256 instead. Everything happens in your browser; your data stays on your device.

About MD5
MD5 is a 1991 hash function (RFC 1321) by Ron Rivest. It is cryptographically broken and should be used only for non-security checksums.
- Output: 128 bits / 16 bytes / 32 hex characters
- Status: BROKEN for collision resistance since 2004 — never use for security
- Safe uses: file integrity (accidental corruption), cache keys, deduplication
- Unsafe uses: passwords, digital signatures, certificates, HMAC, anything adversarial
- Replacement: SHA-256 for general hashing; bcrypt / Argon2id for passwords
