Software and Downloads

  • FlexiProvider
    The FlexiProvider is a powerful toolkit for the Java Cryptography Architecture (JCA/JCE). It provides cryptographic modules that can be plugged into every application that is built on top of the JCA. The goal of our project is to supply fast and secure implementations of cryptographic algorithms which are easy to use even for developers who are not well-footed in the field of cryptography. The FlexiProvider has been developed by the Theoretical Computer Science Research Group of Prof. Dr. Johannes Buchmann at the Departement of Computer Science at Technische Universität Darmstadt, Germany.

  • ArchiSoft

    The probative value of electronic signatures has to be preserved over a long period of time. This ensures that the legal requirements for electronic document archiving can be met, e.g. in health care and banking. To meet this need, researcher at the Fraunhofer SIT developed the software ArchiSoft. ArchiSoft preserves the quality of digital signatures. If digital signatures are maintained by ArchiSoft, they can be verified for decades, even if cryptographic algorithms or parameters have expired. It provides components both for the long-term conservation of electronic signatures and the subsequent verification of the archived, electronically signed documents.

    For further informations about and access to the online shop please visit the ArchiSoft webpages of Fraunhofer SIT .
  • MobileSitter
    The MobileSitter enables users to administrate their secret codes like passwords, PINs and TANs safely on mobile end devices (e.g. mobile phones). A user can thus access this information at any time and anywhere, at the computer in the office, at home or at the ec-card terminal. With the MobileSitter the user only has to remember one single password – the master password. All other secret codes are stored safely. MobileSitter is a product developed by researchers at the Fraunhofer SIT.

  • Digital Watermarking
    Nowadays most media are created digitally and modern multimedia software facilitates media processing enabling everybody to change media and also manipulate them. The Media-Security-Group at the Fraunhofer SIT in Darmstadt therefore uses and develops different technologies in order to protect digital media data, focussing on digital watermarking. Watermarks allow to protect data integrity and copy rights or ensure trustworthiness of media. Further applications are innovative added-value services. Companies and agencies that are interested in watermarking technologies find more information and licensing option at the Media-Security-Group webpages
