changes on entering a password and locked _which prevents changes ever being made.
If the contents of a document can be decrypted in order to view it theres no way to then lock it against changes, or prevent people printing it etc, using open source code.
However it should be relatively easy to automatically compare signed
documents
(storing the signatures in a database) with newly opened documents, and
pop up a message, eg "this document was signed by you on dd/mm/yyyy, and is
a valid copy" if you didn't get such a message you would know the document had been
tampered with.
You could even have corporate signature database eg this document was signed by your boss, coworker etc.
