內容簡介
內容簡介 A digital signature is a mathematical scheme for verifying the authenticity of digital messages or documents. A valid digital signature, where the prerequisites are satisfied, gives a recipient very strong reason to believe that the message was created by a known sender (authentication) and that the message was not altered in transit.This book is a step-by-step guide on how to create a digital signature certificate in PDF software, how to create templates for three different types of digital signatures, and examples of what a digital signature looks like. This book also explains the difference between "Electronic Signatures" and "Digital Signatures".
