What is the algorithm used in hashing the invoice, Because I need to implement it in my project

@Mahmoud66

  1. Open the invoice XML file.
  2. Remove UBLExtension, QR and Signature tags.
  3. Remove the XML version.
  4. Canonicalize the Invoice using the C14N11 standard
  5. Hash the new invoice body using SHA-256 (output). e.g.:a11b6fe587a50f7daffe3a7fb42dcccf32b43ee9b37d9f252d04243e54c11a3f
  6. Encode the hashed invoice using base64 (output)
    Using HEX-to Base64 Encoder
    e.g.:oRtv5YelD32v/jp/tC3MzzK0PumzfZ8lLQQkPlTBGj8=
