This is an example I just created by building a OSSL_PARAM array with OSSL_PARAM_construct_xx and calling EVP_PKEY_get_params. I've been wondering if this is more efficient than getting the parameters one at a time using multiple EVP_PKEY_get_xx_param which also calls EVP_PKEY_get_params. I've removed trailing nulls from the unsigned integer fields where the returned data size is always the buffer size.
