That's your problem there. Key transport (which EVP_SealInit uses) can only be
done with RSA keys.
Steve.
This might be a dumb question, but what is `key transport` and why doesn't ECC
support it?
Is this is a case where OpenSSL implementation of ECC doesn't support it, or
where ECC isn't a suitable algorithim to use for envelope encryption?
