[Pki-devel] [PATCH] 629 Fixed NPE during key-retrieve.

Keys archived through the KRA connector in CA have null data type attribute which causes a NPE during retrieval using the key-retrieve CLI. The SecurityDataRecoveryService has been modified to consider null data type attribute as asymmetric key type. The KeyRetrieveCLI and KeyService have been modified to generate better debugging messages to help troubleshooting. -- Endi S. Dewata
