One of the biggest criticisms leveled Facebook are related to privacy and security. For that reason it is seeking all ways to change this. This time, they added the ability to encrypt emails that are sent so that no one can intercept on the road. Not even them.
The technology that will be used is OpenPGP and to activate this system must be configured PGP public key in the account just entering information contact section. Once this is done, all emails out from the social network can not be seen by anyone but the recipient.
PGP stands for Pretty Good Privacy, which in English is something like Pretty Security good and is a system created in 1991 by Phil Zimmermann used to encrypt virtual contents through a public and private key. It quickly became one of the most important tools related to network security.
How does it work?
The technicality behind this system may be the most complex, but It can most simply summarized. PGP is making use four different encryption processes that make up a message (or any file) is virtually impossible to hack without the necessary key.
In the encryption process which happens is that the text is compressed, and a random key is generated. When the data packet is sent encrypted with the key of the recipient, which at the time of decrypting the file or document, make the reverse key can decrypt only person who is attached.
In this way will be receiving the message.
How do I create my PGP key?
The simplest application to create a PGP key is Gpg4win, a very simple free application for use with which should only follow a few simple steps and is continuously updated.
What do I do?
Chema Alonso, A computer security expert, he explains in his blog that when the key is added PGP “message will be received in the mail account established communications.” “This message carries encrypted URL of confirmation of the encrypted communication for the future, so it is a good way to ensure that you could decipher the message,” says the hacker.
What if I lose or forget the PGP key?
During the setup of public key there are many alerts in which the social network makes it very clear that if the user loses the PGP key and Facebook password will be no way to recover the account.
