+Linux kernel integrity subsystem is comprised of a number of different
+components including the Integrity Measurement Architecture (IMA),
+Extended Verification Module (EVM), IMA-appraisal extension, digital
+signature verification extension and audit measurement log support.
+
+The evmctl utility is used for producing and verifying digital
+signatures, which are used by the Linux kernel integrity subsystem. It
+is also used for importing keys into the kernel keyring.
+
+Linux integrity subsystem allows to use IMA and EVM signatures. EVM
+signature protects file metadata, such as file attributes and extended
+attributes. IMA signature protects file content.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
