MD5 Hash Generator
Free MD5 hash generator — compute the MD5 checksum of any text in your browser. MD5 is legacy and not collision-resistant; use for checksums only.
MD5 is cryptographically broken. Use it only for non-security checksums and legacy compatibility — never for passwords or signatures.
Runs entirely in your browser — nothing you enter is uploaded or stored.
Compute an MD5 digest
Generates the 128-bit MD5 hash of your text as a 32-character hexadecimal string, entirely in your browser. MD5 is still common for file checksums, cache keys and older integrations, so a quick generator is handy.
Security note: MD5 has been considered broken for years — collisions can be produced on demand — so it must not be relied upon for anything security-critical. Prefer SHA-256 or stronger for integrity and authentication.
Frequently asked questions
Is MD5 secure?
No. MD5 is cryptographically broken — practical collision attacks exist. Never use it for passwords, digital signatures, or security-sensitive integrity checks. It remains useful only for non-security checksums and interoperating with legacy systems.
Why not use WebCrypto?
Browsers deliberately do not expose MD5 through the WebCrypto API because it is insecure. This tool implements MD5 in plain JavaScript instead.
What encoding is used?
The input text is encoded as UTF-8 bytes before hashing, and the digest is shown as lowercase hexadecimal.
Is my input uploaded?
No — everything runs locally in your browser. Nothing leaves the page.
