Signal: In the era of online espionage, the only way you can protect your privacy is encryption, something Edward Snowden has repeatedly mentioned.
The manufacturer of applications Open Whisper Systems made a significant step in this direction today with the release of a new version of the application Signal for iPhone and iPads.
The new version, Signal 2.0.1, supports encrypted messages text using a protocol called TextSecure. In addition to text encryption, it also supports voice encryption. So you can be absolutely sure that your communications, even if they are intercepted while in transit over the internet, cannot be used.
Σε αντίθεση με άλλα προϊόντα κρυπτογράφησης μηνυμάτων κειμένου, ο codes of the Signal app is open source, which means it can be checked at any time by experts.
The app also features the feature forward secrecy, so if an attacker manages to intercept the encryption key you're using, they won't be able to decrypt messages that may have been collected in the past.
Signal for iPhone secures your communications, and you can be sure they will always be fully encrypted. Other encryption applications have unpredictable behaviors at unpredictable times. Apple's iMessage, for example, uses strong encryption, but only when communicating between two συσκευών της Apple και μόνο όταν υπάρχει σωστή connection δεδομένων. Διαφορετικά, το iMessage αποστέλλει μηνύματα SMS σε μορφή απλού κειμένου. Το iMessage δεν υποστηρίζει το χαρακτηριστικό forward secrecy και ο πηγαίος κώδικας του είναι κλειδωμένος.
The Open Whisper Systems application also offers power users the ability to verify the identity of the people they are talking to, confirming that their encryption is not under attack. With iMessage, you just have to trust Apple for that.
