In a text adopted at a summit in Brussels on Thursday, June 22, EU leaders opened the door to cracking encryption of digital services like Whatsapp as a counter-terrorism measure. The text, which was amended at the last minute to include language about privacy, says there is a need to address "challenges posed by systems that allow terrorists to communicate in ways that competent authorities cannot access, including end-to-end encryption." Messaging services like Whatsapp use so-called end-to-end encryption to make sure that its users can communicate without anyone else listening in.
