[Autocrypt] How to create the "raw key" part from an RSA key

[Bjoern]

Hi Hernani,

thank you very much for your post. It's great to hear, netpgp is not
dead and is maintained by PEP now. At a first glance, netpgp seems
much easier to use than GPGME and GnuPG.
(when I had a first look into the PEP code some weeks ago, I only
noticed the dependencies to GPGME/GnuPG and stopped reading ... thanks
for clearification).

The API seems to be unchanged, so maybe Delta will switch to netpgp-et
then (in fact, all the keyhandling stuff is already implemented by
Delta Chat itself using the Autocrypt approach, so, thanks to OpenSSL
and libEtPan, there are only very functions really needed; maybe Delta
Chat will not use any lib for that)

Best regards,
Björn
