This is a command-line implementaton of the pwdhash algorithm in Go. It was mostly ported from the JavaScript version in the Firefox Add-on. This fork of peterh/pwdhash is more secure in that it does not permit the user to put the root password as a CLI argument, which can get saved to bash history files.
Usage
pwdhash <domain>
The prompt is interactive. The output may be piped to tools like pbcopy for convenient pasting.
