Take the 2-minute tour ×  I'm about to encrypt two of my hard
drives using LUKS, since I can't really do it myself I use the
guide on the Arch Linux wiki (which can be found here). In an
example in the guide the cipher specified is aes-xts-plain with
a 512-bit key size. Is aes-xts-plain the best choice or is there
a better cipher to use? I'd prefer security over speed.
share|improve this question If you'd like more comprehensive
answers, then perhaps you could list the ciphers supported by
LUKS by their common names. I don't know which ciphers LUKS
support, and I imageine others here have it the same way. –

on your original post on SU, for most purposes, the level of
security required should be enough that an attacker has no
reasonable chance of breaking it in a useful timeframe (eg for
your personal data, you might want that to be a 10 year span).
So in this example assuming you don't have national secrets or
sensitive corporate data on your
