Recognize the KW and KWP block cipher modes as key wrap algorithms and add the WRAP and UNWRAP usage flags to the KEY_WRAP algorithm category. Currently, only AES-KW and AES-KWP are supported by tf-psa-crypto. Signed-off-by: Tim Pambor <tim.pambor@codewrights.de>
Add exercise_key_wrap_key() to exercise key wrap keys using wrap and unwrap operations and add the WRAP and UNWRAP usage flags to the key usage flags returned by mbedtls_test_psa_usage_to_exercise(). Signed-off-by: Tim Pambor <tim.pambor@codewrights.de>
