   3 NAME
   4      tc – Create and interact with trustcaches
   5
   6 SYNOPSIS
   7      tc append [-u uuid | 0] infile file ...
   8      tc create [-u uuid] [-v version] outfile file ...
   9      tc info [-c] [-h] [-e entrynum] file

  11 DESCRIPTION
  12      The tc utility is used to get info about and modify Apple trustcaches.
  13
  14      The following commands are supported by tc:
  15
  16      append [-u uuid | 0] infile file ...
  17              Modify the trustcache at infile to include each signed Mach-O in
  18              the specified path.  uuid is used to specify a custom uuid to be
  19              used.  If it is 0, the uuid will be left the same, otherwise, it
  20              will be regenerated.
  21
  22      create [-u uuid] [-v version] outfile file ...
  23              Create a trustcache at outfile.  Each Mach-O found in the
  24              specified inputs will be scanned for a code signature and hashed.
  25              Any malformed or unsigned Mach-O will be ignored.  Each slice of
  26              a FAT binary will have its hash included.  Versions 0 and 1 are
  27              supported, if not specified, 1 is assumed.  If uuid is specified,
  28              that will be used instead of a randomly generated one.
  29
  30      info [-c] [-h] [-e entrynum] file
  31              Print information about file.  The output for each hash will be
  32              in the format:
  33
  34                    <cdhash> <flags> [<hash_type>]
  35
  36              If the -c is given, only the hashes will be printed.  If -h is
  37              given, only the header will be printed.  If entrynum is
  38              specified, only that entry will be printed.
  39
  40 EXIT STATUS
  41      The tc utility exits 0 on success, and >0 if an error occurs.
