Possiblity of porting to Java/rust?

[RESDXChgfore9hing]

I wanted to use challenge-response algorithms for my own homemade desktop app using the api shown in. https://docs.yubico.com/yesdk/users-manual/application-otp/challenge-response.html

Is it possible?Or is there any similar api?

Hi @RESDXChgfore9hing,

I think the quickest way forward for you would be to look at using our C library for the OTP application: https://github.com/Yubico/yubikey-personalization

You could write some bindings using JNI for Java or using Rust's FFI capabilities.

You would use ykp_write_config to write the challenge response config to a particular slot - or you could just use one of our existing tools like ykman.

To compute the response given a challenge, you would use yk_challenge_response.

You can see an example command line app for computing a chal/resp here: https://github.com/Yubico/yubikey-personalization/blob/master/ykchalresp.c

Hope this helps!

thanks noted will try it out.
