Perl

Create ICP-Brasil Compliant CMS Signature

See more CAdES Examples

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

# Note: This example creates a CMS signature (.p7s) that contains the PDF.
# It is different than signing a PDF.  To sign a PDF where the resulting PDF contains the CMS signature,
# see this example:  Sign PDF for ICP-Brasil
