LUKS Iterations2025-08-02
Quick reminder to check/increase the iterations on your LUKS keyslots. Default autodetection can for example result in quite low settings such as 3 iterations at 512MB cost if your CPU is slow. I recommend setting 16+ iterations at max 4GB cost. Do note that this can cause unlocking to take 15+ seconds.
