PyKCS11 is a PKCS#11 wrapper for Python. It lets you access almost all PKCS#11 functions and data types using any PKCS#11 library, such as the various modules supplied by smartcard vendors. It comes with two interfaces: a low level and very thin interface over the original PKCS#11 API, generated using the SWIG compiler (designed for library tests), and a high level interface that offers simpler access (with few limits) to the PKCS#11 APIs.
KOSd is a modified version of Ascend's RADIUS (derived from Livingston's) daemon that supports GECOS password files in another location than /etc/passwd. The path to the file is configurable in a C file. It's great for segmenting dial-in and email-only users on a dialing pool, supporting both Max units and Xylogics (now Bay) servers from a single password file, and probably others. It will probably work with Cisco or Livingston servers as well by changing the dictionary file and turning off the -DASCEND extensions within the makefile, but you may need to experiment. This product is totally unsupported.
KNoFault is a tool that protects your files with XOR encryption. It can use a username and a password to encrypt, or it can any file as a key. When given an incorrect decryption key, instead of showing an error it will encrypt the already encrypted file with the new info. This makes it possible to encrypt a file several times so that only two people together can use it, for example.
NordicEdge Certificate Services gives Web service providers a simple path to integrate x509 certificate authentication, digital signatures, and automatic self-registration with their existing authentication infrastructure. Users can be authenticated by HTTPS client certificates or by a simple WebServices API. The vast majority of x509 certificates are supported, both from major vendors and internal enterprise certificates. Supported signature types are PKCS#7, S/MIME, and XML Digital signatures.
