Bug Fix(es):

* When using a P11SecretKey for both signing and encryption in FIPS mode, the FIPS PKCS11 provider would fail with a CKR_ATTRIBUTE_VALUE_INVALID error. This was due to the default configuration not applying the CKA_ENCRYPT=true attribute to the key. The configuration in this release is updated to include this attribute.
