MD5 Generator

About the MD5 Hash Generator

The MD5 Hash Generator turns any text or file into a fixed 32-character hexadecimal fingerprint. The same input always produces the same hash, and even a single-character change produces a completely different one, which is why MD5 is still widely used to verify that a downloaded file matches the original, to deduplicate records in a database, to generate cache-busting keys, and to identify Gravatar avatars from email addresses.

How to use it

1. Type or paste the text you want to hash into the input box, or click the file upload area to hash a file’s contents.
2. Click Generate MD5.
3. Copy the 32-character hash from the result field.

Where MD5 is still appropriate

MD5 is a good choice when you need a fast, compact, non-cryptographic checksum: verifying that a file transfer completed correctly, comparing two large strings for equality without storing them, building deduplication keys for analytics events, generating ETag values for HTTP responses, or computing the hash that Gravatar uses to map an email address to an avatar URL.

Where MD5 should not be used

Researchers have published practical collision attacks against MD5, so it is no longer safe for digital signatures, SSL certificates, password storage, or any context where an attacker might benefit from finding two inputs that hash to the same value. For password hashing use bcrypt, scrypt, or Argon2. For digital signatures or certificate fingerprints use SHA-256 or SHA-512.

Privacy and speed

Hashing runs inside your browser using the Web Crypto API or a pure-JavaScript MD5 implementation. The text or file you submit is never transmitted to our server, so you can safely hash sensitive content during development and testing. Even multi-megabyte files complete in well under a second because no upload step is required, which makes the tool comfortable to use from a phone on a slow connection.
