OTP code generator

Authy etc are annoying GUI apps that require smartphones or Chrome extensions. This is stupid, since you can do the same thing in ~100 lines of C.

How

0. Run make
1. Store base32-encoded token in tokens dir:

echo -n KM4TGS2RK5CTSQKTGBDECRCGHFATAU2G > tokens/footoken
chmod 0600 tokens/footoken

2. Run otp footoken
3. Cut and paste, or pipe output to xclip.

FAQ

1. Shouldn't you encrypt the tokens? Yes. But this program doesn't. Sorry.
2. What about QR codes? You'll need to solve that with other software. Sorry.
3. Where do my tokens go? See Makefile.
