Open small-zz opened this issue 4 years ago • 3 comments

Hello, the hardware platform is ESP8266, the output of running this script is "5E93D75 F2CD44EC FB0E1A5F 85F55271 EEDB6707", and the result given in the process is "// should output: // 40322845 BBB9E97C 6D23ECFA 275581DF 4143C5A2", is there any solution? Thanks

Thanks for your feedback. Unfortunately I currently lack time and an ESP8266 to test your case. Please let me know if you found any solutions.

Do the other example scripts work as expected?

I have tried your HMAC generation and it seems to be a wrong implementation. It generates the same HASH output for the same msg with different keys!!!

Thank you for your comment. Unfortunately I was not able to confirm your observation by running the example program with multiple SimpleHOTP instances.

Can you please elaborate on your issue by sharing the relevant source code lines?
