I recommend requiring a button press to issue the response, but it should work either way.

Ensure that the challenge is set to fixed 64 byte (the Yubikey does some odd formatting games when a variable length is used, so that's unsupported at the moment). First, configure your Yubikey to use HMAC-SHA1 in slot 2. KeeChallenge works using the HMAC-SHA1 challenge response functionality built into the Yubikey. You should check that the DllImport statements in Yubiwrapper.cs match the file names of the binaries you have obtained. It should (hopefully) build without problems once this is done. Open the top level solution and adjust the references to point at your installed KeePass.exe.

Prebuilt bundled binaries are available from. It also requires the Yubico open source library yubico-personalization (which in turn depends on yubico-c). KeeChallenge requires KeePass2, available from. See the OSX Guide by Markku for detailed instructions on how to do this. The same technique will work on OSX, but getting the 32bit Yubico libraries requires building from source. Put both KeeChallenge.dll and in the KeePass2 folder (on Ubuntu this is /usr/lib/keepass2). Make sure all of the Yubico libraries are installed where mono can find them (for example, /usr/lib). For this to work, you must also obtain the appropriate versions of the Yubico libraries. To run under Linux using mono, you must modify and add a dllmap entry to let Mono know where to find the native libraries. DownloadĪs of v1.0.1 both Windows and Linux (Ubuntu) have been tested successfully.
