Lightfactor UAF Authentication Library

lightfactor-uaf is a FIDO UAF 1.0 compliant library that provides register, deregister, authenticate and transaction confirmation support for UAF operations. It is designed to be used in conjunction with lightfactor-engine which provides HTTPS server connectivity to the library.

Lightfactor Identity Engine (the combination of lightfactor-uaf and lightfactor-engine) participated in the August 2016 FIDO Interop event and was certified by FIDO in September 2016. It has been load-tested against a free-tier AWS instance and can support 200 simultaneous UAF operations in that configuration.

This library was designed and built with an emphasis on scalability and simplicity with regard to installation, dependencies, architecture, etc. It is offered here, in Open Source form, to educate, drive further adoption of FIDO, and expand the FIDO ecosystem. No warranty is offered or implied.

Source code review is appreciated, and contributions are welcomed and encouraged.
