Create ICP-Brasil Compliant CMS Signature

Demonstrates how to create a .p7s signature that contains a data file, which in this case is a PDF. The .p7s will be compliant with the ICP-Brazil Digital Signature Standard.
The .p7s file created by this example can be verified at ICP-Brasil Online Verifier
