PKCS#7 style signature containers can be used in iText version 2.

I'm not an expert, though, on how to do that using iText alone as I'm using
external libraries to generate the signature container.

If I were you, I would inspect the samples once again and look for
"/adbe.pkcs7.detached" or PdfName.ADBE_PKCS7_DETACHED.

But maybe someone else can give a pointer more on target...

As you mention PAdES... for that you definitively have to switch to using
CMS containers instead of PKCS#1.

Regards,   Michael.
