Description:

When using a key file with cryptsetup, it's possible to specify a sector offset and key size so that only a portion of the supplied key file is used.

This patch adds that capability to the "encrypt" hook for initcpio. The revised synopsis is shown below.

cryptkey=/dev/<partition2>:<fstype>:<path>:<offset>:<size>

This is already supported when the keyfile is a block device but not when it is a file.


Additional info:
* /usr/lib/initcpio/hooks/encrypt
* cryptsetup 1.6.6-1

This feature request compliments another request: FS#42851 - [cryptsetup] Add support for detached LUKS header to encrypt hook


Steps to reproduce:
