A digital signature creator is a program or device that allows users to create their own unique digital signatures. Some programs, such as Microsoft Word, offer automatic options for users to create customized digital signatures.
A digital signature, which is also known as a digital ID, is a mathematical certificate that encrypts documents with a unique stamp, which makes them difficult to recreate and duplicate. This signature is often necessary in legal documents that people sign online. Many government forms require such a signature for safety and to verify that the person's input information is accurate and belongs to her.
