I wrote a simple test to generate some keys using Crypto++.  The test 
worked fine for any curve I chose in the Prime field.  When I chose curves 
in the Binary field, that's where things pretty much go wrong.  The test 
consisted of the following:

CryptoPP::OID CURVE_283 = CryptoPP::ASN1::sect283r1();

CryptoPP::ECMQV<CryptoPP::ECP>::Domain mqvA(CURVE_283);


This generates an exception saying basically that it doesn't know OID 
sect283r1.  I presume that is because the Binary field math is 
unimplemented, as all the Prime field OIDs seem to work.  Is this the case? 
 If not, is there something I need to do to use sect283k1 and sect571k1? 
 (I believe both OIDs for k1 and r1 curves are available, but in my case 
I'm pretty sure I need the Koblitz curves instead of the Random, but both 
would be even better).

If it is unimplemented, has anyone worked on implementing the Binary field 
for Crypto++?  I see a lot of code for Prime field ECC and little to no 
code for Binary field ECC out there to use as an example.  I started 
looking at the Crypto++ library because it seemed to be more complete. 
 However, I am not sure it is now.

Thanks for reading and any answers you can provide.
