random seed

kast uses a random seed string to ensure that key generation is secure.

you should type a random string that would be difficult for someone else to guess. In general, pounding out "garble" on the keyboard, including both letters and numbers, should be fine.

if an attacker can guess your random seed string, then he or she can re-generate your sender key---in other words, the attacker could send broadcasts on your channel, pretending to be you.
