CLI programs have existed for decades. no browser or connectivity needed. more private, more composable
going to a random stranger's website (with a 2 day old account, and new no-history GitHub account) to generate one's privacy-critical passwords or hashes is particularly insecure and insane. glaring antipattern. trusting that "it always only runs in your browser" is foolish.

there are safer, less brittle and more modular and scalable ways of doing all the above. avoid it, kids
shame on everyone involved
