Example: Crypt2.GetSignedAttributes method

Demonstrates how to call the GetSignedAttributes method. Ruby

require 'chilkat'

success = false

crypt = Chilkat::CkCrypt2.new()

bdPkcs7 = Chilkat::CkBinData.new()
success = bdPkcs7.LoadFile("qa_data/cades/CAdES-T/Signature-C-T-1.p7m")
if (success == false)
    print bdPkcs7.lastErrorText() + "\n";
    exit
end

json = Chilkat::CkJsonObject.new()
json.put_EmitCompact(false)

sbJson = Chilkat::CkStringBuilder.new()
i = 0
tryNext = true
while tryNext
    if (crypt.GetSignedAttributes(i,bdPkcs7,sbJson) == true)
        json.LoadSb(sbJson)
        print i.to_s() + ": " + "\n";
        print json.emit() + "\n";
    else
        tryNext = false
    end

    i = i + 1
end
