This function creates a command that directs the HSM to process a response message using the given data, and to return a result in the form of a reply.
The response message processing is only applicable to hardware and software Digipass compliant with the Secure Channel protocol.
The response message processing on the HSM is identical to the functionality available with the Authentication Suite Server SDK Software Digipass Secure Channel Service. For information on the associated functions, refer to the Authentication Suite Server SDK C-C++ Programmer's Guide.
This function serializes an important amount of data. The Cmd buffer must be allocated with a sufficient size. For more information about the allocation of the Cmd and InReply buffers, refer to Cmd and InReply buffers allocation
This function must be used with the post-HSM API AAL2ProcProcMessageResponseRpl.

Description
aat_byte *
Cmd
O
Up to 2462 bytes that serialize the RESPONSE MESSAGE PROCESSING command type and the input data to the response message processing function on the HSM:
Command type - 2 bytes
PayloadKey BLOB - 72 characters
Runtime parameters - 80 bytes
StorageKeyName - up to 128 characters
InitialVector - 8 bytes
ResponseMessage - up to 1070 characters
Request Message - up to 1070 characters
Host time - 4 bytes
Plus 28 bytes for Authentication Suite Server SDK internal use.
aat_int32 *
CmdSize
I/O
On entry, this parameter contains the size of the Cmd buffer.On exit, this parameter contains the length of the Cmd message.
aat_ascii *
PKBlob
I
Contains the payload key BLOB that has been generated for the Digipass instances activated with a particular serial number license (in case of the multi-device licensing model) or that has been imported for the Digipass authenticator with a particular serial number license (in case of single-device licensing model). The payload key BLOB parameter is mandatory only if the information message is protected (encrypted and/or signed); can be NULL or empty if the information message is not protected (neither encrypted nor signed).
TKernelParms *
CallParms
I
Structure of runtime parameters to use during this function call.
aat_ascii *
aStorageKey NameIn
I
String of up to 128+1 characters, left-justified, null-terminated, or right-padded with spaces. This is the label of the HSM storage key used to encrypt the sensitive Digipass application BLOB data.
aat_ascii *
aIVIn
I
String of 16 hexadecimal characters, left-justified, null-terminated, or right-padded with spaces. This is the initial vector used to encrypt the sensitive authenticator application BLOB data.
aat_ascii *
ResponseMessage
I
Hexadecimal character string containing the response message that has been generated by the Digipass client device in reply to a request message. The string length must be a multiple of 2 with a maximum length of 1070 characters.
aat_ascii *
RequestMessage
I
Hexadecimal character string containing the request message that has been used by the Digipass device to generate the response message. String length must be multiple of 2 with a maximum length of 1070 characters.
