The EVP_PKEY_ASN1_METHOD function export_to() must check that the key we're trying to export has a known libcrypto method, i.e. is a built in RSA_METHOD, DSA_METHOD, etc. Otherwise, the method may be defined by the calling application, by an engine, by another library, and we simply cannot know all the quirks hidden behind that method, if we have access to the key data, or much anything. Such keys are simply deemed impossible to export to provider keys, i.e. have export_to() return 0. This cascades back to functions like evp_pkey_export_to_provider() and evp_pkey_upgrade_to_provider() and their callers. In most cases, this is fine, but if these get mixed in with provider side keys in any function, that function will fail.
