Digital Signature Files, also known as Digital Signatures or Public Keys, are a secure and legally binding form of digital verification. These files serve as electronic proof that the document associated with them is authentic – meaning the contents have not been altered since being signed by the authorized person. A digital signature file ensures that documents remain secure and unaltered throughout the entire transfer process and it can be used for everything from verifying business contracts to protecting intellectual property. With a Digital Signature File, you can rest easy knowing your information is safe and sound.
