   7         boolean "Digital signature verification using multiple keyrings"
   8         depends on INTEGRITY && KEYS

  11         help
  12           This option enables digital signature verification support
  13           using multiple keyrings. It defines separate keyrings for each
  14           of the different use cases - evm, ima, and modules.
  15           Different keyrings improves search performance, but also allow
  16           to "lock" certain keyring to prevent adding new keys.
  17           This is useful for evm and module keyrings, when keys are
  18           usually only added from initramfs.

  21         boolean "Enable asymmetric keys support"

  28         help
  29           This option enables digital signature verification using
  30           asymmetric keys.

  32 config INTEGRITY_AUDIT
  33         bool "Enables integrity auditing support "
  34         depends on INTEGRITY && AUDIT
  35         default y
  36         help
  37           In addition to enabling integrity auditing support, this
  38           option adds a kernel parameter 'integrity_audit', which
  39           controls the level of integrity auditing messages.
  40           0 - basic integrity auditing messages (default)
  41           1 - additional integrity auditing messages
  42
  43           Additional informational integrity auditing messages would
  44           be enabled by specifying 'integrity_audit=1' on the kernel
  45           command line.
