MUNGE(1)		  MUNGE	Uid 'N'	Gid Emporium		      MUNGE(1)

NAME
       munge - MUNGE credential	encoder

SYNOPSIS
       munge [OPTION]...

DESCRIPTION
       The  munge  program  creates an MUNGE credential	containing the UID and
       GID of the calling process.  Additional payload data  can  be  encapsu-
       lated  in  as  well.   The returned credential can be passed to another
       process which can validate its contents (e.g.,  via  the	 unmunge  pro-
       gram).	This allows an unrelated and potentially remote	process	to as-
       certain the identity of the calling process.

       By default, payload input is read from  stdin  and  the	credential  is
       written to stdout.

OPTIONS
       -h, --help
	      Display a	summary	of the command-line options.

       -L, --license
	      Display license information.

       -V, --version
	      Display version information.

       -n, --no-input
	      Discard all input	for the	payload.

       -s, --string string
	      Input payload from the specified string.

       -i, --input file
	      Input payload from the specified file.

       -o, --output file
	      Output the credential to the specified file.

       -c, --cipher string
	      Specify the cipher type, either by name or number.

       -C, --list-ciphers
	      Display a	list of	supported cipher types.

       -m, --mac string
	      Specify the MAC type, either by name or number.

       -M, --list-macs
	      Display a	list of	supported MAC types.

       -z, --zip string
	      Specify the compression type, either by name or number.

       -Z, --list-zips
	      Display a	list of	supported compression types.

       -u, --restrict-uid uid
	      Specify  the  user name or UID allowed to	decode the credential.
	      This will	be matched  against  the  effective  user  ID  of  the
	      process requesting the credential	decode.

       -U, --uid uid
	      Specify  the user	name or	UID under which	to request the creden-
	      tial.  This requires root	privileges or the CAP_SETUID  capabil-
	      ity.

       -g, --restrict-gid gid
	      Specify  the group name or GID allowed to	decode the credential.
	      This will	be matched against  the	 effective  group  ID  of  the
	      process  requesting  the credential decode, as well as each sup-
	      plementary group of which	the effective user ID of that  process
	      is a member.

       -G, --gid gid
	      Specify the group	name or	GID under which	to request the creden-
	      tial.  This requires root	privileges or the CAP_SETGID  capabil-
	      ity.

       -t, --ttl integer
	      Specify  the  time-to-live (in seconds).	This controls how long
	      the credential is	valid once it has been encoded.	 A value of  0
	      selects  the default TTL.	 A value of -1 selects the maximum al-
	      lowed TTL.

       -S, --socket path
	      Specify the local	domain socket for connecting with munged.

EXIT STATUS
       The munge program returns a zero	exit code when the credential is  suc-
       cessfully  created  and returned.  On error, it prints an error message
       to stderr and returns a non-zero	exit code.
