Create .p7s Compliant with ICP-Brazil Digital Signature Standard

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.

Important: This example requires Chilkat v9.5.0.92 or later.

Ruby

require 'chilkat'

success = false

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

crypt = Chilkat::CkCrypt2.new()

# Any type of file can be signed.  It doesn't have to be a PDF.
inFile = "qa_data/pdf/helloWorld.pdf"

bd = Chilkat::CkBinData.new()
success = bd.LoadFile(inFile)
if (success == false)
    print "Failed to load " + inFile + "\n";
    exit
end

# Get the certificate we'll be using to sign.
cert = Chilkat::CkCert.new()

success = cert.LoadPfxFile("qa_data/pfx/cert_test123.pfx","test123")
if (success == false)
    print cert.lastErrorText() + "\n";
    exit
end

success = crypt.SetSigningCert(cert)
if (success == false)
    print crypt.lastErrorText() + "\n";
    exit
end

# Set properties for signing...
crypt.put_HashAlgorithm("sha256")

jsonSigningAttrs = Chilkat::CkJsonObject.new()
jsonSigningAttrs.UpdateInt("contentType",1)
jsonSigningAttrs.UpdateInt("signingTime",1)
jsonSigningAttrs.UpdateInt("messageDigest",1)
jsonSigningAttrs.UpdateInt("signingCertificateV2",1)
