End-to-End Encryption Comes to Skype Through Signal Partnership

Microsoft is testing a new "Private Conversations" feature in Skype, which is being introduced through a partnership with Signal. Skype is using the Signal Protocol for the feature, allowing users to take advantage of strong end-to-end encryption for more secure communications. Private Conversations are available for one-on-one conversations on Skype, with users able to initiate a private conversation by tapping on the "+" icon and then selecting "New Private Conversation." Once a conversation is initiated, it will be available only on the specific device where it was started. Microsoft says Private Conversations offer several unique features: A Private Conversation will have a lock icon next to your contact's name. Preview messages from Private Conversations will not show in Chats or notifications. Private Conversation capabilities are limited. You cannot edit a message or forward a file. From the chat window, only emoticons, files and audio messages are available to send. Private Conversations are specific to a device. A new invitation must be sent and accepted, to change to another device. Private Conversations are available today in a preview capacity for Skype Insiders, Microsoft's beta testing program for

Signal Encrypted Messenger 2.19 Update Finally Available Following App Store Hiccup

Encrypted messaging app Signal pushed out its v2.19 update late on Friday after a post-release 48-hour delay, owing to an App Store issue that Apple has now resolved. The update includes a number of new features and improvements, including full UI display support for iPhone X. After the update is applied, users will no longer see the "Load Earlier Messages" link within chat threads, because additional messages now appear automatically upon scrolling to the top of a conversation. In other improvements, a new simplified interface has been introduced to the Signal mobile app that aims to make sending photos, files, and GIFs easier and quicker. For example, attachment previews are now displayed directly in the message bar instead of on a separate confirmation screen. Adopting a design concept popularized by Facebook Messenger known as "Jumbomoji", emoji characters are now also visibly larger in Signal chat bubbles that don't contain any other text. Elsewhere, messages that fail to send have been made easier to spot and re-send, while a new "Tap for More" option should make navigating extremely long messages a more pleasant experience. The list of supported languages has also been expanded to include Burmese, Hebrew, and Persian, while users with an external keyboard linked to their device can now make use of new key combination shortcuts for sending messages (Shift + Enter, and Command + Enter). Apart from the above changes, Open Whisper Systems has revamped the layout code to improve performance and flexibility, so everything should feel smoother and more

Encrypted Messaging App 'Signal' Approved for Use by U.S. Senate

The U.S. Senate has approved popular encrypted messaging app Signal for official use by staffers in the chamber, it was revealed yesterday (via ZDNet). The news came in a letter sent on Tuesday by Senator Ron Wyden (D-OR), known to be a staunch privacy advocate, in which he underlined his belief that "backdoor-free" encryption should be embraced by the state at all levels rather than something the government should fear. I have long argued that strong, backdoor-free encryption is an important cybersecurity technology that the government should be embracing, not seeking to regulate or outlaw. My own Senate website, which has used HTTPS by default since 2015, was the first Senate website to do so. With the transition to default HTTPS for all of the other Senate websites and the recent announcement by your office that the end-to-end encrypted messaging app Signal is approved for Senate staff use, I am happy to see that you too recognize the important defensive cybersecurity role that encryption can play.Signal by Open Whisper Systems is widely considered by security experts to be the most secure mobile messaging platform on iOS and Android, due to features like end-to-end encryption of text, picture, and video messages, support for private calling, and a lack of separate logins. Members of Congress are for the most part exempt from record-keeping laws, so long as encrypted communications are not "historically valuable", or do not include committee documents. However, workers of the federal government and those who work directly with the president are governed by

Signal Privacy Messenger Users Advised to Turn Off CallKit Support in Latest Update

Encrypted communications app Signal received an update yesterday that enabled video calling for the first time, but the latest version also brings CallKit support to the platform, which may leave some privacy-conscious users wary. Introduced in iOS 10, the CallKit SDK allows incoming calls from third-party VoIP apps to appear on the iOS lock screen and recent calls list, just like standard cellular IDs do. The concern among the privacy community is that their call data – including who they called and how long they spoke for – could be synced to iCloud. In a blog post announcing the new beta features, Signal developers Open Whisper Systems noted that like video calling, CallKit integration is optional, and those concerned about data leakage can turn the support off in settings (Settings -> Advanced -> Use CallKit). The developers also told Wired that in the future, CallKit might only display "Signal users" in an iPhone's call log, to prevent the disclosure of identifying information. Back in August, Russian security firm Elcomsoft discovered that iPhones automatically send a user's call history to the company's servers if iCloud is enabled, but the data gets uploaded in many instances without any user notification. The fear among privacy-minded users is that state actors could theoretically gain access to this information through cooperation with Apple, or that hackers could crack iCloud passwords and break into accounts. More recently Elcomsoft revealed that when iPhone and iPad users permanently deleted their Safari browser history off their devices, iCloud
