How to create a Digital ID (Signature) in Adobe Acrobat Reader?

Before you can add digital signature in PDF file, you need to get a digital ID, sometimes called a digital certificate. Certificates for digital signatures are normally issued by a trusted third party provider called a Certificate Authority (CA), who are certified to do this. Ordering certificates from Certificate Authority often costs you some money depending on the type of certificate you need.

The JSL IT Department adds a digital signature for you when you receive the laptop for the first time. Digital signatures are also set to expire. If the digital signature expired, you can create a new digital ID with Adobe Acrobat Reader if you like.
