The open source MSS library Laverca has been updated to version 2.1.0. The latest release contains extended support of Advanced Electronic Signatures (AdES).
The new Laverca release contains support for additional ProfileQuery extensions. The release allows applications to fetch end user certificates directly from the MSSP. This simplifies signature request processing.
