/*
* ossl_store_handle_load_result() is initially written to be a companion

*
* This result handler takes any object abstraction (see provider-object(7))
* and does the best it can with it. If the object is passed by value (not
* by reference), the contents are currently expected to be DER encoded.
* If an object type is specified, that will be respected; otherwise, this
* handler will guess the contents, by trying the following in order:
*
* 1. Decode it into an EVP_PKEY, using OSSL_DECODER.
* 2. Decode it into an X.509 certificate, using d2i_X509 / d2i_X509_AUX.
* 3. Decode it into an X.509 CRL, using d2i_X509_CRL.
* 4. Decode it into a PKCS#12 structure, using d2i_PKCS12 (*).
*
* For the 'file:' scheme implementation, this is division of labor. Since
* the libcrypto <-> provider interface currently doesn't support certain
* structures as first class objects, they must be unpacked from DER here
* rather than in the provider. The current exception is asymmetric keys,
* which can reside within the provider boundary, most of all thanks to
* OSSL_FUNC_keymgmt_load(), which allows loading the key material by
* reference.
