Code snippet to get access to encrypted payload:

string inputFile = @"c:\pdf.pdf";
Document document = new Document(inputFile);
if (document.EmbeddedFiles[1].AFRelationship == AFRelationship.EncryptedPayload)
{
    if (document.EmbeddedFiles[1].EncryptedPayload != null)
    {
        // document.EmbeddedFiles[1].EncryptedPayload.Type == "EncryptedPayload"
        // document.EmbeddedFiles[1].EncryptedPayload.Subtype == "MicrosoftIRMServices"
        // document.EmbeddedFiles[1].EncryptedPayload.Version == "2"
    }
