xorkeesign lets you verify PDF documents signed by any application. It also verifies signatures where xorkee handles are used in place of digital certificates.

Documents that are not in PDF format but signed with or without a digital certificate in CMS format or XML signature format can be verified here. Even old documents signed in raw PKCS#1 format can be verified.

The verification operation is carried out locally in your browser.
