The new DSS v5.6 features independent document timestamping, a complete rewriting of major components and several fixes.

The newest release, available as of 2 March 2020, brings new exciting opportunities to use the Digital Signature Services (DSS) beyond its former scope. The framework now allows independent documents without a signature, such as PDFs, to be also timestamped. The new version features a complete rewriting of the TL and LOTL loading with improvements including multi-lingual support in trust service matching, as well as an online/offline refresh. Furthermore, issues reported during the vulnerability and conformance testing are now fixed. Detailed release notes are available at the download link above.

For those unfamiliar with the DSS, it is an open-source software library intended for Service Providers active in the implementation electronic signature solutions. Its main functionalities support the creation and validation of electronic signatures in line with European legislation; and its development closely follows the eIDAS Regulation and related standards.

The CEF eSignature Building Block maintains a DSS demonstration tool that is available to anyone interested in test running its functionalities. For more information on the DSS, what it is and how it can be used, visit our website:
