Yubikey Core

Depends on Yubico PIV Tool

Compiling the library

gcc uniris-yubikey.c -o uniris-yubikey -lykpiv -lcrypto -c

Testing with a driver

gcc driver.c -o driver uniris-yubikey -lykpiv -lcrypto
./driver

One step driver compilation

gcc driver.c -o driver uniris-yubikey.c -lykpiv -lcrypto
./driver

Compiling Yubikey-core for Elixir support

Make sure that Erlang and Elixir are already installed on the system.

gcc support.c -o support stdio_helpers.c uniris-yubikey.c -lykpiv -lcrypto

Required commands at the start of a new session
