Hello Nikita, we already have a HMAC module in libavutil, so you could try to implement "The AES-CMAC Algorithm", RFC 4493. Michael, would this be acceptable for you? Giorgio Vazzana 2014-10-12 19:17 GMT+02:00 Nikita Mantri : > Hi, > Thanks for your response. I want to contribute to this projec

I am aware of that there are already two candidates who are working on this project, but I still want to give it a try. For the qualification round, suggest me some task. I can implement the hash functi
