The purpose of a digital signature is the same as your handwritten signature. Instead of using pen and paper, a digital signature uses digital keys (public-key cryptology). Like the pen and paper method, a digital signature attaches the identity of the signer to the document and records a binding commitment to the document. Unlike a handwritten signature, It is considered impossible to forge a digital signature the way a written signature might be.
The real value is in avoiding the paper and keeping your data electronic.
To use digital signature software requires some initial setup: you will need a signing certificate. If in your business you commonly sign documents or need to verify the authenticity of documents, then digital signatures can help you save time and paper-handling costs. The DigiStamp web site and software is designed to help you with the process and allow you to take advantage of the convenience and power of digital signatures.
