We solve all your doubts about digital certificates and electronic signatures

How does the service guarantee the confidentiality of the documents to be signed?

Through the virtual machine that we deliver to you and that will be installed in your infrastructure, we guarantee the confidentiality of the information to be signed. The original documents are sent to the virtual machine, then it makes the calculation of the hash (mathematical algorithm that transforms data blocks into a new series of characters) and sends it to the Uanataca service which is where the pure electronic signature is produced.

It is materially impossible to reconstruct the original document from the hash. Once the signed hash returns to the virtual machine, the electronically signed document is composed there. The original information never leaves your infrastructure.
