Signal: Στην εποχή της διαδικτυακής κατασκοπείας, ο μόνος τρόπος που μπορείτε να προστατεύσετε την ιδιωτική σας ζωή είναι η κρυπτογράφηση κάτι που το έχει αναφέρει επανειλημμένως ο Edward Snowden.
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 text messages 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.
Unlike other text encryption products, Signal's code is open source, meaning it can be reviewed at any time by specialists.
The app also features forward secrecy, so if an attacker manages to intercept it key encryption you use will not be able to decrypt messages that may have been collected in the past.
Signal for your iPhone ensures your communications, and you can be sure they will always be fully encoded. Other encryption applications have unpredictable behaviors at unpredictable times. Apple IMessage, for example, uses strong encryption, but only when communicating between two Apple devices and only when there is a proper data connection. Otherwise, iMessage sends SMS messages in plain text. IMessage does not support the forward secret feature and its source code is locked.
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.
