Peerio is designed by 24-year-old Nadim Kobeissi the creator of the end-to-end encrypted group messaging app Peerio, released on Wednesday. Peerio avoids complexity of the PGP key management by requiring users to create as long as 30 character passphrase that is then used to create a 100-bit entropy private key. The free version of the app only gets 1.2 GB in storage, and the Peerio team intends to sell premium features, such as more storage, as its business model.
