XML Advanced Electronic Signatures (XAdES)

XML Advanced Electronic Signatures are defined in the ETSI standard  ETSI TS 101 903 V1.1.1.

 OpenXAdES implements that standard in a library, and  GNU DigiDoc a graphical user interface application built on top the libdigidoc (AKA OpenXAdES).

libdigidoc uses PKCS#11 for smartcard access on non-windows platforms and works well with OpenSC.
