Comment (by zwol):

 Yes, definitely use Elligator instead of the mess I made up.  You may also
 want to replace AES-GCM with something that's more likely to run in
 constant time.  AES-OCB might be usable now, depending where the funding
 is coming from (OCB is patented; there's a blanket license for open source
 use, but there's also a clause specifically forbidding use for military
 purposes, which could be read to extend to anything funded by military
 tentacles of the government).  ChaCha/Poly1305 might also be a good
 choice.  In general, I have come around to the opinion that I should have
 trusted DJB instead of NIST when I designed this thing.
