Signal and other encrypted messaging services have always kept the contents of messages sent on their platforms hidden in encrypted form. However until recently, information about who is sending and receiving messages was still accessible to third parties, including government agencies.
On October 29, Signal published a post on its blog announcing the new “sealed sender” feature for Signal. Signal still needs to know who it needs to deliver the message to, but shouldn’t need to know where the message is coming from. Before this latest update, Signal used the sender’s identity to “help prevent spoofing and provide the recipient with some assurance about who sent the message.”
