'Stamped' documents

Mdas AB registers the original SHA256 checksum of 'stamped' electronic documents and data files in order to enable later verification of their authenticity. These files are given an id consisting of six letters or numbers added to their filename. The filename can be changed, but the id of the file must be retained. To retrieve the original checksum, send an email with the file id as the first line, in the body of the email, to chksum@mdas.se. The original checksum will be automatically returned within a few minutes. The files's current SHA256 checksum can be found here. Changes to a document alters it checksum. If the original and current checksums are identical, the file has not been changed.
