```c
/* End-to-end-encryption and other cryptographic functions based upon OpenSSL
and BSD's netpgp.
If we want to switch to other encryption engines, here are the functions to
be replaced.
However, eg. GpgME cannot (easily) be used standalone and GnuPG's licence
would not allow the original creator of Delta Chat to release a proprietary
version, which, however, is required for the Apple store. (NB: the original
creator is the only person who could do this, a normal licensee is not
allowed to do so at all)
So, we do not see a simple alternative - but everyone is welcome to implement
one :-) */
