Albarubens issues ATEX certificates and laboratory test reports.
They are not public documents, because most of them contains reserved information; so they are not available for free download to general public.
All Albarubens documents include digital signature, using the *.pfx format.
Albarubens is always capable to distinguish true signatures by fake ones, but it's intended for internal purposes only.
The main user interest is to check if the received certificate of test report was really issued by us or artificially created by somebody else.
This authentication system assumes that you are already in possession of the document, wishing to check for its authenticity.
So you can read the document name and password, present on the cover of the document itself: see the yellow boxes in the example picture.
Type in the certificate name (ie ARyyATEXnnn or ARyyTESTnnn) into the 'Search' box, then click the "SEARCH THE DATABASE" button.
Click on the 'Download' button and type the password as requested by the system.
The system will download the official copy, to be compared to the one in your possession.
If they are identical it's OK, if not (very likely) your copy is a fake.
In this case please contact our office (firstname.lastname@example.org), in order to inform us about the problem; there is also the remote possibility of a technical problem.
Security is enforced because this connection is protected and encrypted.
