General Requirements

User Interface

  • Microsoft Edge (latest version)
  • Microsoft Internet Explorer (all versions supported by Microsoft)
  • Mozilla Firefox (latest version)
  • Google Chrome (latest version)
  • Apple Safari (latest version)

Administration Interface

  • Microsoft Edge (latest version)
  • Mozilla Firefox (latest version)
  • Google Chrome (latest version)

Due to the short release cycles of Firefox and Chrome and their integrated update functionality every version of Cryptshare will only be tested and optimized against the most recent version available. In general the Cryptshare User Interface is compatible with older versions of these browsers as well. However, we do not recommend to use these. Instead an update to the latest version should be performed.

HTML 5 Upload Mode

This upload mode is the most advanced transfer mode currently available. It is therefore only supported in recent browser versions. These include

  • MS Internet Explorer version 10 or higher
  • Google Chrome v.40 or later
  • Mozilla Firefox v.35 or later


For the HTML 5 upload mode full Javascript support is required. Settings or Browser add-ons which may reduce the capabilities of Javascript may lead to errors during the upload process.

Internet Explorer

Although Internet Explorer 10 and 11 have HTML5 support, this transfer mode may still not be available due to the settings of the Compatibility Mode. This mode is usually active by default for sites within the local Intranet.

Compatiblity Mode must be deactivated

Please make sure, that the compatibility mode is deactivated. Otherwise the HTML5 upload mode will not be available.
