To prefer the provider-based hardware offload, you can specify the default
properties to prefer your provider.
Setting engine-based or application-based default low-level crypto method such
as B<RSA_METHOD> or B<EC_KEY_METHOD> is still possible and keys inside the
default provider will use the engine-based implementation for the crypto
operations. However B<EVP_PKEY>s created by decoding by using B<OSSL_DECODER>,
B<PEM_> or B<d2i_> APIs will be provider-based. To create a fully legacy
B<EVP_PKEY>s L<EVP_PKEY_set1_RSA(3)>, L<EVP_PKEY_set1_EC_KEY(3)> or similar
functions must be used.
