Identify a file by MD5 (legacy systems)
file = (select any file)
Result: Select a file to see its MD5 hash.
File MD5 Hash Generator
Compute the MD5 hash (digest) of a file in your browser. MD5 produces a 128-bit (32 hex character) fingerprint. ⚠️ WARNING: MD5 is cryptographically broken and should NOT be used for security purposes such as password hashing, digital signatures, or certificate verification. It is still useful for quick file identification and legacy system compatibility.

Frequently asked questions
Is MD5 secure?
No. MD5 is cryptographically broken — collisions can be generated in seconds. It should never be used for password hashing, digital signatures, or security verification. Use SHA-256 or SHA-3 for security-critical applications.
Why would I use MD5 at all?
MD5 is still used for non-security purposes: file identification, legacy system compatibility, and checksums where collision resistance is not required.
Is my file uploaded?
No. The file is processed entirely in your browser using the Web Crypto API. Nothing is sent to any server.
