A: CertyFirma uses advanced technology, such as blockchain-based electronic signatures, to guarantee the integrity and validity of an entire document with a single digital signature. This eliminates the need to sign each individual page of a document, offering a more efficient and practical solution.

When a document is sent to be signed with Certyfirma, it is encrypted with a unique fingerprint that protects all its content from possible alterations. That is why it is not necessary to sign each page, since the integrity of the document is assured from the very moment it is sent thanks to its digital fingerprint.
