Hi All
Are here developers from the UK?
How to create IRMark during sending xml file to HMRC?
I've generated an XML document and need to do the following:
- Canonicalize (14N) the XML Document
- Generate a 160-bit binary secure has from the canonicalized xml using SHA-1 algorithm
- Encode the binary data using base-64 to produce a 28 characters string
- Encode the binary data using base-32 to produce an easily humanreadable 32 characters string
IRMark generation step by step is here
