Google announced on Tuesday (3) an extension for Chrome browser called “End-to-End”. The program allows Internet users to read and protect messages with OpenPGP encryption protocol.The tool is not yet available in the Chrome Web Store since Google just released the source code for specialists to check the security software before distributing it-who find security holes can receive cash rewards.
The “End-to-end” can be used to protect communications, especially the content of e-mail.
The name of the software, “end-to-end” (end to end, in Portuguese), is a technical term from the branch of cryptography. Are situations in which a data is protected at source to be decrypted only by the recipient. This means that not even Google can read messages protected with the “end-to-end”: there is not any kind of “master key”, as in the system developed for use by the Brazilian federal government .
The Gmail email service from Google, already protects messages in transit when possible, but the email providers of internet users who are communicating must have support this feature. Google has released data on the number of messages that this encryption in transit is possible: 69% of messages leaving Gmail and 48% of those arriving are encrypted ( See here ). Such encryption, however, does not protect the surfer in the event of a court order to verify the e-mail provider, or if the email itself is compromised by hackers.
In the case of “end-to-end”, netizens involved in communicating themselves must have the extension installed and generate a key pair for communication. If the key is lost, the protected messages can not be read because there is no other means of accessing data. Justice authorities also have difficulty accessing messages, unless a flaw is discovered in the program. That’s why Google decided to provide the code before the extension itself.
The tool, which should be free, and no release date. The ad says that it should only occur when the Google “feel she is ready.”
