Important Update Notes

42274358.svgQUICK Technology


Please check the Compatibility of your add-on products.


QUICK Technology considerably simplifies the use of Cryptshare! Instead of having to exchange one-time passwords manually, QUICK will take over the management of passwords for your users so they don’t have to deal with passwords anymore but can send and receive information passwordless. For more information please use the following links:

Verification reset recommended
QUICK Technology only works on the highest possible security level if secure QUICK verification tokens can be used. This can only be guaranteed if all previously issued verification tokens have been invalidated during the post update step.

It is therefore highly recommended to invalidate existing verifications during the post update. 42274360.png


  • No invalidation:
    • Cryptshare and QUICK Technology work without any constraints.
    • QUICK does not work on the highest possible security level.
  • Invalidation:
    • QUICK will work on the highest possible security level.
    • All users will need to perform a verification again.

Impact on performance

Please note that due to the technical complexity of the QUICK Technology an increased consumption of resources on the Cryptshare Server is expected. It is therefore recommended to check the general utilization of the system before updating and, if necessary, provide additional system resources in order to use QUICK. The average increase is approx. 15%.

Language Packages

Due to structural changes in the language packages, all supported server language packages will be updated automatically, customized language packages will be removed during the update process (a backup is done before). If more language packages are needed, it is required to download and install them again.

Password Reset for administrative access After Cryptshare has been updated to v4.3.0, only users with administrative privileges will be able to login into the administration interface. During the post update procedure, all passwords for users with administrative access will be reset. This means:

  • After the post update has been initiated, only the administrator who initiated the update will be able to login afterwards.
  • Other administrators cannot login until the initiating administrator has triggered a password-reset for these users.


Show example ....

Three users with administrative setup exist:

  • 'administrator': The default Cryptshare administrator account.
  • 'johndoe': A user of type 'user' is only allowed to see the status-section.
  • 'janedoe': A user of type 'administrator' who has full administrative access.

In this example, 'administrator' is the one who runs the post update.

Before the post update:

  • 'administrator' and 'janedoe' may login.
  • 'johndoe' is not allowed to login at all due to missing access permissions.

After the post update:

  • 'administrator' is able to login.
  • 'janedoe' and 'johndoe' cannot login. An error message will be shown.

To do for 'administrator': The user 'administrator' needs to navigate to the section 'User Administration' and initiate a password reset for 'janedoe' and 'johndoe'.


Changed Cipher Suites

Changed Cipher Suites
Please note, that the update changes the cipher suite configuration of the Jetty server. The following cipher suite setting will be applied:
<Set name="includeCipherSuites">
            <Array type="java.lang.String">
        <Set name="excludeCipherSuites">
            <Array type="java.lang.String">
If you have adjusted your cipher suite configuration, please apply these changes after the update again. The update will not migrate changed settings.
