Description

This function is used to generate a request message from a clear request body, using the payload key embedded into the payload key BLOB.

The payload key BLOB must be the one corresponding to the Digipass serial number the request message will target.

The request message generation is only applicable to hardware and software Digipass compliant with the Secure Channel protocol.

Parameters

Table: Parameters (AAL2GenMessageRequestICSF)
Type	Name	Use	Description
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 *	aStorageKeyNameIn	I	String of up to 64+1 characters, left-justified, null-terminated, or right-padded with spaces. This is the label of the ICSF storage key used to encrypt the sensitive Digipass application BLOB data.
aat_ascii *	aInitialVectorIn	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 *	MessageVector	I	A string of up to 26+1 characters containing the message parameter settings, null-terminated (obtained during import).
aat_ascii *	RequestBody	I	Hexadecimal character string containing the clear request body to use for generating the request message. The string length must be a multiple of 2 with a maximum length of 1024 characters.
aat_ascii *	RequestMessage	O	A string of up to 1070+1 hexadecimal characters, null-terminated. In case of a successful operation, this parameter contains the generated RequestMessage.
aat_int32 *	RequestMessageLength	I/O	In input, this parameter must indicate the size of the allocated buffer for the RequestMessage parameter (recommended 1071 bytes). In output, this parameter indicates the length of the RequestMessage string (without the null-terminated character).
