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.


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:
This task depends upon
