OP_keymgmt_get_params() should extract information data associated

OP_keymgmt_gettable_params() should return a constant array of

OP_keymgmt_settable_params() should return a constant array of

has ensured that I<keydata_to> and I<keydata_from> are both owned by
the implementation of this function.

The value should be the number of security bits of the given key.
Bits of security is defined in SP800-57.
-=item "use-cofactor-flag" (B<OSSL_PKEY_PARAM_USE_COFACTOR_FLAG>,
-B<OSSL_PKEY_PARAM_USE_COFACTOR_ECDH>) <integer>
-
-The value should be either 1 or 0, to respectively enable or disable
-use of the cofactor in operations using this key.
-
-In the context of a key that can be used to perform an Elliptic Curve
-Diffie-Hellman key exchange, this parameter can be used to mark a requirement
-for using the Cofactor Diffie-Hellman (CDH) variant of the key exchange
-algorithm.

-See also L<provider-keyexch(7)> for the related
-B<OSSL_EXCHANGE_PARAM_EC_ECDH_COFACTOR_MODE> parameter that can be set on a
-per-operation basis.
