(SQL Server) Cape Verde Fatura Eletrónica XML Digital Signature

See more XML Digital Signatures Examples

Demonstrates how to sign XML to create a signed invoice compatible with the Cape Verde Fatura Eletrónica requirements.

Note: This example requires Chilkat v9.5.0.89 or greater for a small feature to provide the ability produce mult-line base64 signature ending with 

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows
