This is proving more complex than I had hoped.  In particular, the
EVP_PKEY_*() functions make the assumption in several places that the
only asymmetric cryptosystem capable of encryption and decryption is
RSA.

I could fix this, but I'm uncomfortable designing the new structures
which would be necessary, since the OpenSSL project would likely
define them differently if they ever implement El Gamal.

Was I assuming too much when I assumed that OpenSSL would be a useful
framework for implementing cryptosystems not currently used by SSL or
TLS?
