Viber defends new end-to-end encryption protocol against criticism | TechCrunch

Viber contines to not specify protocol

“Viber will not grant backdoor access under any circumstance and in any country. We agree with the stance both Apple and WhatsApp have taken. Viber can access records that show only that one phone number has contacted another phone number. However we cannot access the content of messages or phone conversations,” the spokesperson added.

“Our encryption protocol was based on an open source protocol concept, with an extra level of security developed in-house,” the spokesperson explained.
