As with the identity card, which must include the handwritten signature of the person, in the digital certificate There must be an equivalent validation, which is called a digital signature.
It is credible proof that the subscriber of a document is the person they claim to be.
But, unlike the autograph signature, the digital signature consists of a sequence of characters (electronic data) that are obtained by an algorithm in a mathematical way (called asymmetric encryption).
They have particularities that prevent them from being falsified or used to impersonate the identity of the person who created them: They are:
- Unique. Only the one who generated the signature knows it.
- They contain a message and whoever tries to falsify them will have to solve very complex mathematical problems.
- The official who receives a digital document has the necessary instruments to know if the message was read or modified by a third person.
- Easy to generate. The certified authority gives the interested party the instructions required to create the digital signature.
- Undeniable: The person signing a document cannot deny that this is not their signature.
The digital signature is a resource that allows people to sign a wide variety of (electronic) documents, among which are commercial contracts, invoices, invitations, monetary transactions, judicial notifications, credit procedures and, in some cases, even vote online.
In order to have a digital signature, it is necessary to contract the services of entities authorized by the Certifying Authority (BCCR, in our case), which are granted the status of “Certification Service Providers”.
The entity certifies the entity of the signatory and gives him a card with a magnetic stripe, with the information he needs to digitally sign his documents and messages.
