       keyutils - in-kernel key management utilities


       The keyutils package is a library and a set of utilities for accessing the kernel keyrings

       A header file is supplied to provide the definitions and declarations required  to  access
       the library:

              #include <keyutils.h>

       To link with the library, the following:


       should be specified to the linker.

       Three system calls are provided:

              Supply a new key to the kernel.

              Find an existing key for use, or, optionally, create one if one does not exist.

              Control  a  key in various ways.  The library provides a variety of wrappers around
              this system call and those should be used rather than calling it directly.

       See the add_key(2), request_key(2), and keyctl(2) manual pages for more information.

       The keyctl() wrappers are listed on the keyctl(3) manual page.


       A program is provided to interact with the kernel facility by  a  number  of  subcommands,

              keyctl add user foo bar @s

       See the keyctl(1) manual page for information on that.

       The  kernel  has  the  ability  to upcall to userspace to fabricate new keys.  This can be
       triggered by request_key(), but userspace is better off  using  add_key()  instead  if  it
       possibly can.

       The  upcalling mechanism is usually routed via the request-key(8) program.  What this does
       with any particular key is configurable in:


       See the request-key.conf(5) and the request-key(8) manual pages for more information.
