An exception is the java implementation, which is taken from the reference implementation and only slightly modified (to be more production system suitable).
This project contains example implementations of the OATH OCRA Challenge Response algorithm for various languages.
All of the implementations are based on the reference implementation from the official OCRA specification.
The current version of the OCRA standard can be found here:
http://tools.ietf.org/html/rfc6287
Versions currently exist for:
- Java
- Objective-C
- PHP
Each language implementation is accompanied by a unit test that validates the implementation against the test vectors from the RFC.
This project was initiated by SURFnet and developed by Egeniq.
The Java and Objective-c versions were updated from draft-13 to the final RFC specification with support from Innovation District.
The PHP version received bugfix contributions from Andjelko Horvat.
