What is a digital signature?

A digital signature is an electronic signature that is used to verify the authenticity of a digital document.

How to sign and certify PDFs electronically

Create a digital ID

To sign and certify PDFs electronically, you first need to create a digital ID. A digital ID is a unique electronic signature that is used to sign and certify PDFs. You can create a digital ID using Adobe Acrobat Pro or other software tools.

Add a signature field

Once you have created your digital ID, you need to add a signature field to your PDF. A signature field is an area in the PDF where the digital signature will be applied. You can add a signature field using Adobe Acrobat Pro or other software tools.

Sign and certify the PDF

To sign and certify the PDF, you need to apply your digital signature to the signature field. You can do this using Adobe Acrobat Pro or other software tools. When you apply your digital signature, the PDF is encrypted to protect the signature and the document's contents.

Verify the signature

To verify the signature, you or the recipient of the PDF can use Adobe Acrobat Pro or other software tools. The signature is verified by checking the digital certificate and public key associated with the digital ID. If the signature is valid, the PDF is considered to be authentic and has not been altered since it was signed.
