ideviceinstaller fails with ApplicationVerificationFailed

[hk0O7]

Following the Installing via USB steps with the file name in the release the installation fails with a signature verification error:

$ ideviceinstaller --version
ideviceinstaller 1.1.1

This is probably not the right file, though, but I can't find it pre-compiled outside of some random Dropbox link I'd rather not trust.
