Keybase is fine for throwaway encryption that only needs short-term wire security to protect data that will be useless next month. I wouldn't use a keybase key

Keybase is fine for throwaway encryption that only needs short-term wire security to protect data that will be useless next month. I wouldn't use a keybase key for anything that should be rendered eternally unbreakable, based on side-channel threat analysis alone. Private keys are not something that should be sourced from a website.
