Check a Marsa file has not changed

Someone sent you a clearance file made on Marsa. Drop it here and this page works out its fingerprint again from the words on it. If a single word has been changed since it was made, the fingerprints will not match. The file stays in your browser; nothing is uploaded.

What a match proves: the words are exactly the words that were fingerprinted when the file was made. It does not prove who made it; the person named on the file is responsible for the decision it records. Marsa records, it does not clear ships.
