Description
TDigipassBlob *
DPData
I/O
authenticator application BLOB. Upon return from the function call, this BLOB must be rewritten to the application database to reflect changes.
TKernelParms *
CallParms
I
Structure of runtime parameters to use during this function call.
aat_ascii *
Signature
O
String of up to 17 numeric or hexadecimal characters, left-justified, null-terminated, or right-padded with spaces. This is the dynamic password generated by the library (recommended buffer size is 18 bytes).
aat_ascii *
SignedDataFields
I
Array of 8 left-justified, null-terminated, or space-padded strings of max. 20 characters. This parameter holds the 8 possible data fields that are entered into the Digipass authenticator to generate a signature. Digipass data fields are limited to 16 decimal, hexadecimal, or alphabetic characters.
aat_int32
FieldCount
I
Numeric value from 1 to 8 indicating the number of data fields to use from the aSignedDataFieldsIn array.
aat_int32
Deferred signature date
I
Must be 0 if signature is generated in online mode (OnlineSG=1 or 2).
If signature is generated in offline mode with OnlineSG=0 or 3, this parameter can receive the date for the signature generation (number of elapsed seconds since January 1st 1970) or 0 (with 0, the current time is used).
aat_ascii *
Confirmation code
O
String of up to 17 numeric or hexadecimal characters, left-justified, null-terminated, or right-padded with spaces. This is the confirmation code generated by Authentication Suite Server SDK (recommended buffer size is 18 bytes).
aat_int32 *
Confirmation CodeLength
O
Pointer to a long integer that indicates the length of the generated confirmation code.
