Sorry, I'm still not quite getting it.
It sounds like you're saying that only RSA supports encrypting with a
public key. But can't any asymmetric encryption algorithm encrypt using
the public key? Why is RSA special in this regard?

Ok, thanks.
What I don't understand is what key transport has to do with
EV_SealInit() ? Why is key transport important here ?
Because EVP_SealInit() generates a random symmetric key and encrypts it using
one or more public keys. For this to work the public key algorithm has to
support encryption of the symmetric key using a public key aka key transport.
Of the public key algorithms OpenSSL currently implements only RSA has that
operation.
