[Pkg-cryptsetup-devel] Bug#381973: keysize is limited

reassign 381973 partman-crypto

hello,

the reason for your luksOpen error is indeed an unsupported keysize. the
keysize must always be a multiple of 8 bits, and it is limited. see
output of /proc/crypto for limitations.

sha256 supports 256 bits, if you need a bigger key, use cipher sha384.

partman-crypto should limit the keysize for the sha256 cipher to 256.

i will add a note to the cryptsetup manpage.
