A Look Into Signal’s Encrypted Profiles

Signal continues to be my favorite, secure messaging app. I request it of as many of my contacts that will tolerate me. 🙂

To answer the initial question, can this feature get abused for OSINT? I’m doubtful it can. This is certainly state of the art privacy by design: showing a profile name and picture while preserving the E2E confidentiality (server-side data being stored encrypted) and disabling OSINT availability.

You Should Really Consider Installing Signal, an Encrypted Messaging App for iPhone – The Intercept.

In the age of ubiquitous government surveillance, the only way citizens can protect their privacy online is through encryption. Historically, this has been extremely difficult for mere mortals; just watch the video Edward Snowden made to teach Glenn Greenwald how to encrypt his emails to see how confusing it gets. But all of this is quickly changing as high-quality, user-friendly encryption software becomes available.

App maker Open Whisper Systems took an important step in this direction today with the release of a major new version of its Signal encrypted calling app for iPhones and iPads. The new version, Signal 2.0, folds in support for encrypted text messages using a protocol called TextSecure, meaning users can communicate using voice and text while remaining confident nothing can be intercepted in transit over the internet.

Telegram Messenger

Lately I have decided that security and privacy are going to become more important to me. I have decided to move as much of my messaging to secure systems such as Telegram. I suggest you do the same.

Telegram is a cloud-based mobile and desktop messaging app with a focus on security and speed.
