Hi Tim, I don't think it's clear. The spec says that the key format type in the Digest indicates the format of the Managed Object . If the Key Format Type (by itself) may vary, why the key format type in the Digest may not? Also, the only updates I can see in the document from the 1.3 to the 1.4 version (regarding the variable items) are about the "Client Correlation Value" and "Additional attributes", which were added. if last year, with KMIP 1.3, it was accepted to vary the Digest key format type and nothing has changed in the document, why we cannot use it any more?

There is a clearly separate rule for that - and it wasn't accidential that the rule for Digest was not updated to include variable Key Format Type. We have also previously discussed actually removing the variability on Key Format Type from the profiles as well - given that it is causing some interoperability challenges with vendors picking unusual values and then not supporting returning in a more natural format on a Get.

The key format type is a permitted variation according to the KMIP Profiles Version 1.4 document, section 4.1.1, item 12 (Key Format Type). 4.1.1 Variable Items An implementation conformant to a Profile MAY vary the following values: … 12. Key Format Type a. The key format type selected by the server when it creates managed objects Regards, John From: [email protected] open.org [mailto: kmip-interop-tech@list s.oasis-open.org ] On Behalf Of Felipe Kendi Sent: Wednesday, 21 March 2018 6:29 AM To: Mark Joseph < [email protected] > Cc: [email protected] open.org Subject: Re: [kmip-interop-tech] Expected Key Format Type Hi Mark, From the spec (3.17 Digest): "The Key Format Type field in the Digest attribute indicates the format of the Managed Object from which the Digest Value was calculated." In the previous link (variable items): "12. KeyFormatType a. The key format type selected by the server when it creates managed objects " If the "Key Format Type" can vary when when the object is created, then I think the key format type used in the "Digest" varies too.

Looking at the variable items like you provided I did not see that. But I am getting old so maybe I missed it :-).

Kryptus Server returns the Key Format Type as Transparent (this was also our behavior in the last year Interop): <Attribute> <AttributeName type =" TextStrin g " value =" Digest " /> <AttributeValue> <HashingAlgorithm type =" Enumer ation " value =" SHA_256 " /> <DigestValue type =" ByteString " value =" 0533e51dd2ead671fa9eb9 cd08baa7868fe94b42d579b4f0d3cf dacaefbe8688 " /> <KeyFormatType type =" Enumerati on " value =" TransparentRSAPriva teKey " /> </AttributeValue> </Attribute> However, P6R expects the Key Format Type to be exactly like the in the test case: <Attribute> <AttributeName type="TextString" value="Digest"/> <AttributeValue> <HashingAlgorithm type="Enumeration" value="SHA_256"/> <DigestValue type="ByteString" value="8eb422ae2b006a05d3c8a54 2a28536735241b6dc1c37926bc8007 bd6220d9230"/> <KeyFormatType type="Enumeration" value="PKCS_1"/> </AttributeValue> </Attribute> Kryptus' understanding is that the Key Format may vary from server to server, as stated in the "KMIP Protocol Profiles 1.4" document, section 4.1.1 (variable items): http://docs.oasis-open.org/kmi p/profiles/v1.4/os/kmip-profil es-v1.4-os.html#_Toc491431423 P6R thinks different and has informed us that this year the tests were expected to check for the Key Format Type. Can you folks please tell me when this was decided? And if this is indeed the expected behavior, why the profiles document was not updated?
