Signing a PDF file

Hi, anyone knows if pdfium.dll can sign pdfs with a certificate ?

I'm trying to find the info but not sure about it.

I'm actually using batchpdfsign for this problem, but when i open a signed PDF file it says that it's not a valid signature, i'm reading a lot (no idea about this thing of signing pdfs...).

Tried a soft (xolidosign desktop) that can be configured the output file with "cades/cades-c/cades-xl" when i use this last option, it seems everything is correct ... signature valid.

do you know if pdfium can sign this way ? or any idea about this "cades-xl" format ? (remember i'm starting with the signature process and i'm totally new xD)

thanks in advance!

I don't believe so. You can get the signature object and some details but there's no API to write it.

Thanks, I will go for the java path,I think it will be easier

Thanks!
