As an IT system that preserves evidence, the proNEXT Archive Manager generates an electronic archive timestamp for archived documents and signatures and automatically re-signs the hash tree. The component offers all cryptographic extensions that are necessary to ensure the evidentiary value of electronic documents in accordance with Section 71a of the Code of Civil Procedure.

In addition to archives, the software can also be integrated into document management systems and/or e-file solutions and is certified according to BSI 03125 TR -ESOR.

In accordance with the eIDAS regulation is the exact procedure for Germany in the technical guideline BSI TR 03125 (BSI TR-ESOR) clearly described. The BSI also publishes the security-relevant cryptographic algorithms in the form of a catalogue.

So within the framework of long-term archiving that Maintaining the probative value of electronic signatures can be used, the point in time at which the signature was created must be documented conclusively in a suitable "evidence-preserving" IT system. This creates one Archive Timestamp and signs archived documents including their signatures again and again.

If a signed document is then requested from the archive system at any time and it is determined during verification that the cryptographic algorithms and parameters are no longer suitable for security, a Evidence document (with all timestamps generated to date) be proven that this electronically signed document was re-signed in a timely manner and its get legal usability at a hunt.

In contrast to paper documents, the evidentiary suitability of electronically signed documents can "disappear" over time. The reason for this is the Loss of security suitability of cryptographic algorithms. In addition, the directories and documents required for checking certificates may no longer be available.

As a result, when archiving digital documents, it must not only be ensured that these can be found at any time are, but also for one possible evidence in court can be used.

At the filing and storage of electronic documents and data is an implementation of Security goals at the highest possible level of technology necessary. The elementary evidence for this can be found in the Code of Civil Procedure (ZPO) § 371 a "Probative value of electronic documents". This is additionally supported by the Europe-wide applicable eIDAS regulation affirmed.
