yubibomb is a Rust command line tool that prints out a random number that is formatted like a 6-digit yubikey token. You can use it to pretend to accidentally press your Yubikey while your IRC client has the keyboard focus! Usage example:

$ yubibomb
869926

This project is available on crates.io.

yubibomb returns fake HOTP tokens so you can paste them into IRC.
