=head1 NAME
evp_keymgmt_export_to_provider,
evp_keymgmt_clear_pkey_cache
- key material provider export for EVP
=head1 SYNOPSIS
#include "crypto/evp.h"
void *evp_keymgmt_export_to_provider(EVP_PKEY *pk, EVP_KEYMGMT *keymgmt);
void evp_keymgmt_clear_pkey_cache(EVP_PKEY *pk);
=head1 DESCRIPTION
evp_keymgmt_export_to_provider() exports the key material from the
given key I<pk> to a provider via a B<EVP_KEYMGMT> interface, if this
hasn't already been done.
It maintains a cache of provider key references in I<pk> to keep track
of all such exports.
If I<pk> has an assigned legacy key, a check is done to see if any of
its key material has changed since last export, i.e. the legacy key's
is_dirty() method returns 1.
If it has, the cache of already exported keys is cleared, and a new
export is made with the new key material.
evp_keymgmt_clear_pkey_cache() can be used to explicitly clear the
cache of provider key references.
=head1 RETURN VALUES
evp_keymgmt_export_to_provider() returns a pointer to the appropriate
provider side key (created or found again), or NULL on error.
=head1 NOTES
"Legacy key" is the term used for any key that has been assigned to an
B<EVP_PKEY> with EVP_PKEY_assign_RSA() and similar functions.

=head1 DESCRIPTION
All these functions are helpers to call the provider's corresponding
function. They all have in common that they take a B<EVP_KEYMGMT> as
first argument, which they also retrieve a provider context from when
needed. The rest of the arguments are simply passed on to the
function they wrap around.
evp_keymgmt_newdata() calls the method's new() function.
evp_keymgmt_freedata() calls the method's free() function.
(the name evp_keymgmt_freedata() was chosen to avoid a clash with
EVP_KEYMGMT_free() on case insensitive systems, the name
evp_keymgmt_newdata() was chosen for consistency)
evp_keymgmt_get_params() calls the method's get_params() function.
evp_keymgmt_gettable_params() calls the method's gettable_params()
function.
evp_keymgmt_has() calls the method's has() function.
evp_keymgmt_validate() calls the method's validate() function.
evp_keymgmt_import() calls the method's import() function.
evp_keymgmt_import_types() calls the method's import_types() function.
evp_keymgmt_export() calls the method's export() function.
evp_keymgmt_export_types() calls the method's export_types() function.
=head1 RETURN VALUES
evp_keymgmt_newdata() returns a pointer to a provider side key object,
or NULL on error.
evp_keymgmt_gettable_params(), evp_keymgmt_import_types(), and
evp_keymgmt_export_types() return parameter descriptor for importing
and exporting key data, or NULL if there are no such descriptors.
All other functions return 1 on success and 0 on error.

=head1 DESCRIPTION
evp_keymgmt_util_export_to_provider() exports the key material from
the given key I<pk> to a provider via a B<EVP_KEYMGMT> interface, if
this hasn't already been done.
It maintains a cache of provider key references in I<pk> to keep track

its key material has changed since last export, i.e. the legacy key's
is_dirty() method returns 1.
If it has, the cache of already exported keys is cleared, and a new
export is made with the new key material.
evp_keymgmt_util_clear_pkey_cache() can be used to explicitly clear
the cache of provider key references.
evp_keymgmt_util_cache_pkey() can be used to assign a provider key
object to a specific cache slot in the given I<target>.
I<Use with extreme care>.
evp_keymgmt_util_fromdata() can be used to add key object data to a
given key I<target> via a B<EVP_KEYMGMT> interface. This is used as a
helper for L<EVP_PKEY_fromdata(3)>.
=head1 RETURN VALUES
evp_keymgmt_export_to_provider() and evp_keymgmt_util_fromdata()
return a pointer to the appropriate provider side key (created or
