EVP_PKEY_assign_RSA, at least in C, is more type-safe. It also is compatible with an upcoming BoringSSL change to make the RSA struct opaque. For some Swift reasons I don't fully understand (but relating to the OpaquePointer mess), when RSA becomes opaque, EVP_PKEY_assign no longer works.
I assume it could be made to work with some appropriate cast, but since EVP_PKEY_assign_RSA already exists (and will, in the future, be more binary-size-friendly), just use that.
