All PDF documents published on this website are signed with a certificate issued by the Spanish Royal Mint on behalf of the Government of the Principality of Asturias that ensures the accuracy and integrity of the documents.

Adobe Reader 7.0 (and the new versions of Adobe Acrobat Standard and Professional) allows you to check the validity of PDF documents signed with digital certificates issued by the Spanish Royal Mint. Follow the next steps to check the integrity of the electronic signature, as well as the validity of the digital certificate and the time-stamp.

1. Verifications can be obtained in the ‘Signatures’ section, clicking on the icon ‘Signatures’, which is located on the left side of the signed PDF document.
2. The validity of the certificate with which the signature was made can be checked clicking the right button of the mouse on the signature. A menu will be displayed, select the ‘Properties’ option, then select ‘Signature Properties’, select the ‘Summary’ option, and click on ‘See Certificate’.
3. And now you can check the time-stamp of the signed PDF document. Go to ‘Signature Properties’, and select ‘Date and Time’.
