The new BNotK Card will be in Sign Live! C.C.C supported from version 7.1.11.

In the future, the Federal Chamber of Notaries will issue its signature certificates via the remote signature service and no longer via a personal one Signature card provide.
Authentication for signature creation at the remote signature service is carried out using personal means Smart Card.

This requires a completely new approach to signature creation. This signature is not sent via the signature device “signIT smartcard CC” but rather via “signIT BNotK“. When signing, please select the appropriate signature device in the signature assistant. If your signature certificate is not available, please contact the support of the Federal Chamber of Notaries.

If you use a Reiner SCT card reader with an RFID function, be sure to switch off the RFID function so that there are no problems reading the authentication certificate that is on your card.

If you Sign Live! C.C.C from a specialist application, please inquire with the manufacturer whether the new signature device has been connected.  

The presentation of the signature can be designed individually. The procedure is in the tutorial "Design signature field display" described which you here available for download. 
It is important to ensure that the last variable is in the window appearance contains a value. A newline as the last variable would lead to an error message (internal cryptographic library error).

For the qualified electronic signature you need in addition to the Software additionally a Signature card , and a Card reader.
You can obtain signature cards from trust service providers (VDA). The of Sign Live! C.C.C Supported signature cards and card readers can be found in our service description and system requirements.

Purchase the signature application software here Sign Live! C.C.C for different operating systems.

It should be possible to check whether a signature is valid, i.e. valid, even after many years. In order to be able to check a signature again, several pieces of information must be available:

  • Was the end user certificate used valid at the time it was used?
  • Was the issuing CA (Certificate Authority) of this certificate trustworthy and the root certificate valid at the time the end user certificate was created?
  • What was the quality level of the certificate used? Basic, advanced or qualified?

To confidently answer these questions, a validation application such as Sign Live! several exams. An important aspect of this check are revocation checks using OCSP (Online Certificate Status Protocol), ie queries to the trust service provider (VDA) that issued the end user certificate used. In order for these OCSP queries to be carried out, this service must be made available online by the VDA (directory service). The replies from the VDA are in turn signed by the latter so that the trustworthiness can be checked and thus ensured. This is then done in turn with the inclusion of OCSP queries. International standards (ETSI) regulate how this is to be done in full. At the end of these queries, the validation application can then provide a trustworthy status of the end user certificate used.

But what if the necessary directory service is temporarily or permanently unavailable? A temporary disruption can occur if the required directory service is simply not available online. Or what if this was switched off by the VDA being discontinued? The central deletion of information after the retention periods have expired also represents a cut. The end user certificate used cannot be checked in such cases and therefore the complete signature check does not lead to a clear result.

LTV signatures are different. With this type of signature, all required information is embedded in the signature, again according to international standards (ETSI). In the case of PDF documents and signatures, this is technically regulated, for example, by the PAdES standard (ETSI EN 319 142) in the context of the PAdES-B-LT profile.

The necessary information can be embedded both during signature creation and later during validation. However, it is rare for the validation information to be embedded during signature creation, as this would slow down the entire process. In addition to the time required to create the signature, the time for validation would also be added. It is therefore a good idea to enrich the LTV data during validation before archiving. From this point on, the signature is always checked offline and takes place without access to the directory service. A test is therefore independent of the availability of this service, regardless of the reason why it is not available.

Does the LTV signature do even more?

How the validity of certificates is checked is based on different models (chain, shell or modified shell model). These different models also make sense for the different uses of certificates. The validity of an SSL certificate should be checked differently in the browser than a certificate that was used to sign documents that have to be verifiable for decades.

Let's take Adobe Reader as an example. Adobe Reader will no longer classify a signature as trustworthy after the end user certificate used has expired, even if the signature was made during the validity period.

This behavior can be avoided by the LTV signature if the LTV signature is done before the expiration date. With the timely LTV signature, the Adobe Reader tick stays green and the signature continues to be positively checked - permanently. This is an important step on the way to greater user acceptance of the signature.

Are intarsys products affected by the security vulnerability?

The BSI has the following security warning published.
The actual problem is explained in a PDF, which is continuously updated on the BSI website.
 

intarsys products are not affected by the security problem!

You can find the following intarsys products in the supported versions continue to operate without changes:

  • Sign Live! C.C.C
  • Sign Live! CC DATEV edition
  • Sign Live! CC SPARKASSEN edition
  • Sign Live! cloud suite bridge
  • Sign Live! cloud suite gears
  • Sign Live! cloud suite SDK

The Java library that is causing the problem is in these products not .

This also applies to the Archisoft product from FHI-SIT in versions 1.1.1.8 and 1.1.1.9, which is sold by intarsys.

Product-specific explanations

  • In Sign Live! cloud suite gears Third-party products used up to version 8.7 are based on the critical Log4j version 2.14, but in the context of gears the dangerous library log4j-core-*.jar neither delivered nor used. There is therefore no potential risk.
  • With Sign Live! C.C.C delivered Exampleimplementations (SDK / JMS) use Log4j version 1.x. These are only activated by calling the command line on the system and are also required a special Log4j configuration. They are therefore not viewed as a potential hazard.

Further safety information on the required basic components

tom cat 9 does not use Log4j in its basic configuration without standard and other web apps.

General safety information on the required basic components

Use the JVM in the required version (Java 11, SLcs gears: Java 8) at the most current patch level possible.
The Sign Live! CC / PDF / A Live! integrated JVM fulfills this (Java 11).
For Sign Live! cloud suite gears should be at least Azul JDK 8u312 + .

Further background information

If you want to sign from GVS a BNotK card for remote signature, it is necessary that you set this up accordingly in GVS.
You can see an example of the settings here.

Also, please make sure that Sign Live! C.C.C is entered as the software to be used.

If you use software from Baqué & Lauter GmbH as a bailiff and with Sign Live! C.C.C want to sign must in Sign Live! C.C.C a certain "Service" to be set up.

If during the installation of the bailiff software the software Sign Live! C.C.C was already installed, this service should have been set up automatically. Otherwise, this can also be done manually. You will find the corresponding instructions here.

When opening very large files, the Sign Live! C.C.C There is not enough RAM available (error message: … “Java heap space”). The log provides information about the maximum amount of memory Java requires from the operating system, e.g. E.g.:

[2019.11.20-09:29:57.818][I][d.i.tools.logging][executor singleton][] maxmemory=477626368

First, check that the operating system can actually provide that much memory for Java. Operating system and other applications also require memory!
If enough memory is available, please gradually increase the memory claimed by Java.

So put in Sign Live! C.C.C more memory available:

  • Copy the fileINSTALLATION DIRECTORY> \ demo \ vmoptions \ more memory \* .vmoptions1 after \bin.
  • Starten Sie Sign Live! C.C.C New.
  • If the main memory is not sufficient, the value in the vmoptions file can be edited with an editor and the value can be increased to -Xmx2048m, for example. The maximum value depends on how much RAM is available on your computer.

Important note:

  • For operation as a Windows service, the signivecc_service.exe file must also be created with identical content.

1) The name of the vmoptions file depends on the operating system used.

Sign Live! CC starts with the language settings of the operating system.

To get the operating language of Sign Live! CC To manipulate it, you need administrator rights.
Follow these steps:

  1. Quit Sign Live! CC.
  2. Use Windows Explorer to switch to the installation directory for Sign Live! CC. This is in most cases "C:\Programme\Sign Live CC <version>" oder "C:\Programme (x86)\Sign Live CC <version>".
  3. Navigate further into the subdirectory "demo\vmoptions\language english".
  4. Copy the SignLiveCC.exe.vmoptions file from this directory.
  5. Change to the “bin” subdirectory of the installation directory Sign Live! CC and drop the SignLiveCC.exe.vmoptions file there.
  6. Starten Sie Sign Live! CC new so that the language settings are loaded.

By doing this, the entire user interface of Sign Live! CC presented in English.

To reset to German, delete the file “SignLiveCC.exe.vmoptions” from the bin directory and start Sign Live! C.C.C New.
