FIDOk can serve as a partial ABI-compatible replacement for Yubico's
libfido2. You can compile
and link your C application against a normal libfido2.so.1 (or against FIDOk itself...)
and then at run time use libfidok.so instead.
Example of how to use the drop-in:
gcc my_program.c -lfido2 -o my_program # Compile and link against normal libfido2
ln -s /usr/lib/libfidok.so.1 libfido2.so.1 # Create symlink that points to libfidok
env LD_LIBRARY_PATH=. ./my_application # Run with symlink in LD_LIBRARY_PATH ahead of real libfido2Of course, placing libfidok.so in your system at the /usr/lib/libfido2.so.1 path
would have the same effect.
