Jeff Garzik linked to this article suggesting older (18.04) Ubuntu encrypted disks might be vulnerable to brute-force attacks:

Does Armory offline run on Ubuntu 22.04?
In passing, this made me wonder if the Armory transaction-signing / key-exposing password has any anti brute-forcing mitigations? Could a 20+ mixed character password still survive today's attacks?
