How do I apply digital signatures with UniPDF?

There is a difference between digital signatures and electronic signatures. The latter encompasses digital signatures but also includes the ability to simply print their handwritten signatures onto documents. Whereas, digital signatures involve the use of cryptographic algorithms to provide the most robust and secure electronic signatures.

A document that is digitally signed is legally valid in many countries. This depends on the type of signatures being used. You can use digital signatures to comply with most demanding legal and regulatory requirements as they make it easy to track each of the signer's identity and the authenticity of the documents. UniPDF now allows you to conveniently digitally sign PDF documents using our Golang based library.
