The functionality supports the pattern "open a channel to the repository", "loop and retrieve one object at a time", and "finish up by closing the channel".
The retrieved objects are returned as a wrapper type OSSL_STORE_INFO, from which an OpenSSL type can be retrieved.
Support for the 'file' scheme is built into "libcrypto". See ossl_store-file(7) for more information.
