Summary Digital signature is the effective proof of the PDF veracity. Like the handwritten signature, the digital signature can be signed on the PDF file at any time, as a kind of identification. However, we sometimes need a signature-free PDF file. Do you know how to remove signature from PDF easily?
Digital signature (or, public key signature), is a series of numbers generated by the information sender, which is the effective proof of the information authenticity. Like its paper equivalent, digital signature is a way to identify the authenticity of digital information, based on the technology of public key encryption.
