How work the coding does process?

GPG is a tool of coding and digital companies licensed under the lpg. GPG bases the messages using even of asymmetric individual keys (a private key and public key) generated by the users. Each user maintains his private key safely and shares his public key with all those people who wish to send a based message to him.

Later the two will share their public keys that will be concerned in their client of mail. We have I decide to use Horde, the service of webmail including in all the plans of lodging Web of Carat-Hosting.

Summarizing, Beatriz and Antonia will create their keys GPG through assistant of Horde. Later they will share and concern its respective public keys. At the end of the process messages with the same facility that did it before, but with the security will be able to be sent of which only they will be able to decipher them.

It shares your public key

As we explained in How the coding process works, if you wish that somebody writes a message to you of based mail, you need to share first your public key. Simplest it is to send a message to the person to whom we want to send the key, since the public key will be enclosed automatically to the message because in the previous step we marked the option To enclose default public key GPG to the messages.

Continuing with the assumption, when Beatriz sends a message to Antonia, Horde will identify the enclosed public key of Beatriz and will offer to Antonia the option to concern it.
