installing dnscrypt-wrapper for centos

Hello guys

I hope I can get my answer in this forum.

I am newbie for centos, I want try to install dnscrypt-wrapper to my centos box.

I follow all instruction in https://github.com/Cofyc/dnscrypt-wrapper

but I have problems now, it seem my certificate that I created didn't works.

I tried to make new cert and copying it to dnscrypt-wrapper misc folder, but it didn't works either.

I am always get this warning when I try to login.
