' This example assumes the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.
' This example performs the following calculation:
' 1.5.1 Calculations for manageInvoice and manageAnnulment operations
'
' For the manageInvoice and manageAnnulment operations comprising the core of requestSignature,
' requestSignature is calculated using partial authentication, concatenating the hash values for
' indices 1-100 as well as additional SHA3-512 hash operations. The partial authentication can be
' derived by concatenating the following values:
'
' - requestId value
' - UTC timestamp tag value using a YYYYMMDDhhmmss mask
' - string literal of the technical user�s signature key
'
' When concatenating, the date and time separators as well as the time zone must be removed for timestamp masking.
'
' The index hash value can be derived from the uppercase SHA3-512 hash values following the concatenation of the
' operation and base64 content for the individual indices:
'
' - literal value of invoiceOperation or annulmentOperation
' - base64 content in the invoiceData or invoiceAnnulment tag
'
' The calculated hash values should be appended after the partial hash, in the order corresponding to the indices.
' The SHA3-512 hash result (capitals) of the string thus concatenated yields the requestSignature value.
'
' A fictitious example for request data:
'
' - requestId = TSTKFT1222564
' - timestamp = 2017-12-30T18:25:45.000Z
' - technical user�s signature key = ce-8f5e-215119fa7dd621DLMRHRLH2S
' - the index#1 invoice data items
' - invoiceOperation = CREATE

' - the index#2 invoice data items
' - invoiceOperation = MODIFY
' - invoiceData = RGNiYTQzMjE=
' - partial authentication value = TSTKFT122256420171230182545ce-8f5e-215119fa7dd621DLMRHRLH2S
