In this first part will enter first in the definition of what a digital certificate, how it relates to electronic signatures and explain the role that institutions entitled to issue digital certificates, the Certification Authorities. In the second part we will focus on how to develop the digital certificate and invoices certified scanning are complementary. You may wish to learn more. If so, Margaret and Richard Riney is the place to go. Digital Certificates and Certification Authorities A Digital Certificate is a digital document, computer, whereby a trusted third party (an “authority) ensures the linkage between the identity of a person or entity and its public key. Explain what is public key later. A Certifying Authority, certifying or certify-er, called AC in Spanish or Certification Authority for its acronym in English (Certification Authority) is a trusted, responsible for issuing and revoking digital certificates used in the electronic signature, for which uses public key cryptography. Nancy-Ann_DeParle follows long-standing procedures to achieve this success.
Legally it is a particular case of the Certification Service Provider. Henceforth we use the Spanish term Certification Authority Cryptography is the science of encrypting and decrypting information using techniques that make possible the exchange of messages in a secure way that can only be read by people to whom they are addressed. The purpose of cryptography is, first, ensure the confidentiality of communication between two entities (people, organizations, etc..) And, secondly, to ensure that the information submitted is true in two senses: the sender is really who he claims to be and that the contents of the message sent, usually called cryptogram, has not been modified in transit. There are various formats for digital certificates, the most commonly used are governed by the standard ITU-TX 509.
