MD5 Hash Generator

Generate MD5 hashes of text or files instantly. Useful for legacy checksums, cache keys, ETags and matching old systems — with a clear warning about where MD5 must not be used.

Type or paste text to get its MD5 hash instantly, or drop a file of any size to hash it in chunks on your device. Choose hex or Base64 output, and paste an expected checksum to verify a match. MD5 is fine for checksums but broken for security uses.

MD5 hash

128-bit digest · 32 hex characters · text is hashed as UTF-8

MD5 is cryptographically broken: attackers can create two different files with the same MD5. Use it only for non-security checksums, never for passwords or signatures.
A hash is one-way: it can't be “decrypted”. Sites that claim to reverse MD5 only look the hash up in tables of previously hashed common strings. For passwords, use a slow hash like bcrypt or Argon2 — never plain MD5.

How to use MD5 Hash Generator

  1. 1Choose Text or File.
  2. 2Type the text or drop the file — the hash updates instantly.
  3. 3Pick hex (lower or upper case) or Base64 output.
  4. 4Paste an expected hash to verify a download or value.

About MD5

MD5 produces a 128-bit (32 hex character) digest. It's fast and still common for file checksums, database keys and legacy APIs, and it's perfectly adequate for detecting accidental corruption.

It is cryptographically broken: researchers can create two different files with the same MD5 in seconds. Never use MD5 for passwords, digital signatures, certificates or anything an attacker could tamper with — use SHA-256 instead.

Hashing isn't encryption

A hash function turns any input into a fixed-size fingerprint. The same input always gives the same hash, the smallest change gives a completely different one, and there's no key to reverse it — which is why “hash decrypters” only look up precomputed hashes of common strings.

Hash text for checksums, deduplication and signatures; store passwords with a slow, salted algorithm like bcrypt instead. Verify downloads with the File Hash Checker.

Frequently Asked Questions

Is MD5 secure?

No, not for security. Collisions are trivial to create and MD5 password hashes can be cracked at billions of guesses per second. It's still fine as a non-security checksum.

Can a hash be decrypted?

No. Hashes are one-way. Sites that “decrypt” hashes just search tables of hashes of common words and leaked passwords, which is why short or common inputs can be found and long random ones can't.

Is my data sent to your server?

No. This tool runs entirely in your browser using the Web Crypto API and JavaScript. Nothing you type or generate is uploaded, logged or stored.
