Crash kernel will retrieve the dm crypt keys based on the dmcryptkeys command line parameter. When user space writes the key description to /sys/kernel/config/crash_dm_crypt_key/restore, the crash kernel will save the encryption keys to the user keyring. Then user space e.g. cryptsetup's --volume-key-keyring API can use it to unlock the encrypted device.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
