What is a digital signature?

A Digital Signature is an indispensable tool for digitization. A digitally signed file has the same legal value as a signed paper copy but has many more advantages. It is faster and more efficient because a file can be signed by a PC or smartphone, at any time and in any place. Paper is avoided, helping to reduce costs and protect the environment. Furthermore, a digitally signed file guarantees better integrity and authenticity since any tampering or alteration can be immediately seen.
