The keyrings facility is primarily a way for drivers to retain or
cache security data, authentication keys, encryption keys and other
data in the kernel.
System call interfaces are provided so that userspace programs can
manage those objects and also use the facility for their own
purposes.
A library and some userspace utilities are provided to allow access
to the facility. See keyutils(7) manual page for more information.
