How does end-to-end encryption work in this app:
1. Whenever you send a message M a random symmetric key R is generated
2. R is encrypted using the asymmetric (public) key of the other user resulting in A
3. M is encrypted with R resulting in N
4. If security key S is set: N is encrypted by S
5. N and A is sent to the destination
