We are attempting to create a list of users of botan. If you are using botan for any kind of project it would be great to list your information here; just send a link and whatever other information is useful to the development mailing list or to Jack Lloyd.

Open Source Users

• SoftHSM, an open sourced software PKCS #11 implementation, which is used as part of the OpenDNSSEC project.
• Qt Creator, an IDE for building Qt applications.
• NetSieben's SSH library provides SSLv2 client connections for C++ applications, using botan for the crypto. (GPL or commercial)
• QCA, the Qt Cryptographic Architecture (part of KDE4) uses parts of botan as an embedded crypto provider.
• Silverlock is a GPL password management tool for Windows, OS X, and Linux.

• eVersys is a GPL alternative to Rational ClearCase.
• Monotone, a free distributed version control system, uses botan for RSA authentication, content hashing, and message authentication.
• Publimark, a tool for hiding messages in an audio file.
• KeySafe, a password application for GNOME

Books, Dissertations, Journal Papers

• A Unified Approach to Intra-Domain Security describes a system by researches from Oak Ridge National Lab and Indiana University that uses botan to secure ARP and DHCP.
• CLL: A Cryptographic Link Layer for Local Area Networks describes a network encryption system using botan. (One of the coauthors, Yves Jerschow, also contributed a number of optimizations to the library).
• The project described in Enabling Intrusion Detection in IPsec Protected IPv6 Networks Through Secret-key Sharing by Patrick J Sweeney (a thesis towards a masters from the Air Force Institute of Technology) used botan.
• An experimental tamper detection system designed by researchers from the University of Delaware and the US Army Research Laboratory used botan. As far as I am aware the software was never publicly released.
• A prototype implementation of a telephony signal security system that uses botan is described in the paper Prototyping and evaluation of TCAPsec by Kang Chung and Mathilda Gustafsson.
• Code Reading: An Open Source Perspective, by Diomidis Spinnellis, includes code from an early version of botan (then called OpenCL).
