NAME

7       unmunge - MUNGE credential decoder
8
9

SYNOPSIS

11       unmunge [OPTION]...
12
13

DESCRIPTION

15       The  unmunge program validates a MUNGE credential (e.g., one created by
16       the munge program).
17
18       By default, the credential is read from stdin and the metadata  &  pay‐
19       load  are written to stdout.  When the metadata and payload are written
20       to the same stream, they are separated by a blank line.

OPTIONS

24       -h, --help
25              Display a summary of the command-line options.
26
27       -L, --license
28              Display license information.
29
30       -V, --version
31              Display version information.
32
33       -i, --input file
34              Input the credential from the specified file.
35
36       -n, --no-output
37              Discard all output.
38
39       -m, --metadata file
40              Output metadata to the specified file.
41
42       -o, --output file
43              Output the payload to the specified file.
44
45       -k, --keys string
46              Specify a subset of metadata keys to output.  The keys are case-
47              insensitive  and delimited by whitespace, commas, semicolons, or
48              periods -- as long as the string is treated as a single argument
49              by  the  shell  (e.g.,  enclosed by quotes).  If a subset is not
50              specified, all available keys are selected by default.
51
52       -K, --list-keys
53              Display a list of metadata keys.
54
55       -S, --socket path
56              Specify the local domain socket for connecting with munged.

METADATA KEYS

60       The following metadata keys are supported.
61
62       STATUS The status of the credential decode operation.
63
64       ENCODE_HOST
65              The address of the host on which the credential was encoded.
66
67       ENCODE_TIME
68              The time at which the credential was encoded (according  to  the
69              clock of the host that encoded it).
70
71       DECODE_TIME
72              The  time  at which the credential was decoded (according to the
73              local clock).
74
75       TTL    The time-to-live value (in seconds) placed  within  the  creden‐
76              tial.
77
78       CIPHER The cipher type used to encode the credential.
79
80       MAC    The MAC type used to encode the credential.
81
82       ZIP    The compression type used to encode the credential.
83
84       UID    The user ID of the process that encoded the credential.
85
86       GID    The group ID of the process that encoded the credential.
87
88       UID_RESTRICTION
89              The user ID restriction placed within the credential.
90
91       GID_RESTRICTION
92              The group ID restriction placed within the credential.
93
94       LENGTH The length (in bytes) of the payload.
95
96

EXIT STATUS

98       The  unmunge  program  returns an exit code corresponding to the return
99       code of munge_decode(3).  On success, it returns a zero exit code which
100       signifies  the  credential is valid.  On error, it prints an error mes‐
101       sage to stderr and returns a non-zero exit code.
