Microsoft Enables End-to-End Encryption for Skype
Microsoft has enabled end-to-end encryption this week for Private Conversations on the consumer version of Skype. The feature, which had been announced in January, is now available on Windows, MacOS, iOS, Android, and Linux.
However, the encryption standard only works for a single conversation per device at a time for now. Users can enable the feature from a recipient’s profile or the compose menu to generate an invitation. Once selected, all calls, messages and image/audio/video transmissions will be encrypted until the session is ended.
Skype had previously been using 256-bit AES encryption, which is weaker than end-to-end encryption as it still makes it possible for messages to be accessed on the servers.
