- Copy the hash to compare it with a published checksum or store it as a fingerprint.
Frequently asked questions
What is an MD5 hash?
MD5 turns any input into a fixed 128-bit fingerprint, shown as 32 hexadecimal characters. The same input always gives the same hash, and changing even one character changes the hash completely.
Is MD5 secure?
No — MD5 is broken for security use: collisions can be manufactured, so it must never be used for passwords or digital signatures. It is still fine for simple checksums and non-security fingerprinting. For security, use SHA-256 instead.
Why would I compare MD5 hashes?
To check that a file or piece of text is unchanged. If you hash a download and the result matches the hash published by the author, the file arrived intact.
Does my text leave my device?
No. The hash is computed in your browser with a pure JavaScript MD5 implementation. Nothing is uploaded. Use it as a md5 hash generator free — no signup, nothing to install.
