How to generate a digital signature?

To generate a digital signature it is necessary to use a pair of asymmetric digital keys uniquely attributed to an individual, called the owner. The private key is known only to the owner and is used to generate the digital signature to be affixed to the document. Conversely, the public key is used by anyone who needs to verify the authenticity of the signature. This method is known as double key encryption and ensures complete security since the public key cannot be used to reconstruct the private key. Asymmetric digital keys can be issued only by an ‘Issuing Certification Body’ which guarantees the identity of the signee and must create a Digital Certificate to prove the ownership of public key.

The digital certificate can be contained in a signature device (smart card or USB key) or stored on servers Entity Certifier and recalled by the owner by means of specific software tools ( remote signature). Both methods allow the "private", unique and secret encryption key to be used to affix the digital signature; the related "public" key, on the other hand, made available online by the issuing Certification Body, allows any subsequent verification.

The digital signature can be affixed to any electronic document!
