Make a signing request

To make signature requests, you have to upload the document to be signed to Oamk Sign. For this, you will need separate permissions that can be granted to Oamk staff members only. (If needen, ask more from your manager.)

NB. If you have the right to use both of Oamk’s (OAMK Sign) and the University of Oulu’s (UniOulu Sign) signing service, please use the service related to the task at hand.

If you are sending a request to someone who has more than one email address, please choose (if possible) the email address that is provided by that organisation the signatory is representing when signing the document(s).

Verify the eligibility of a signature made in Oamk Sign

The electronic signature is valid only on the original electronic document. A printed version of an electronically signed document on paper is only a copy, and the electronic signature is not valid on a paper copy. Use Adobe Acrobat Reader to verify the eligibility (integrity and originality) of an electronic signature.

The electronic signature is checked from the pdf document:

  1. Open the pdf file with Adobe Acrobat Reader.
    On the top right side of the signed document is the Signature Panel (or Allekirjoituspaneeli) button. On its left side, you can see text about the electronic certificate (e.g. Certified by Oulun ammattikorkeakoulu Oy <kirjaamo @>, Oulun ammattikorekakoulu, certificate issued by Entrust Class 3 Client CA.)
  2. Click the Signature Panel and you will see the document information (see below). You can e.g. check when the document was signed. If you want, you can click Signature Details (Allekirjoitustiedot) for more detailed information about the certificate.
