{code}
COSString contents = (COSString)
sig.getCOSObject().getDictionaryObject(COSName.CONTENTS);
byte [] ba = contents.getBytes();

> Assume you get a 300+MB large pdf and need to know
> 1) the file names of embedded files if any
> 2) whether it is encrypted (symmetric or asymmetric)
> 3) certification level (and whether it is signed)
> This should not use more than 5 MB (extra) memory
>
