A digital name signature ensures that computer files are authentic and have not been altered. The digital signature, also called a digital certificate, can be created for email, text files, Word documents, Access databases, PowerPoint presentations and just about any kind of file that requires verification of authenticity. A digital certificate can be purchased from a third-party company, but you can create your own digital signature for your Microsoft Office documents and files. A digital name signature is useful when sharing files with others to ensure that no one has changed your original document. Tips Warnings Writer Bio
