unmunge − MUNGE credential decoder
unmunge [OPTION]...
The unmunge program validates a MUNGE credential (e.g., one created by the munge program).
By default, the credential is read from stdin and the metadata & payload are written to stdout. When the metadata and payload are written to the same stream, they are separated by a blank line.
-h, --help
Display a summary of the command-line options.
-L, --license
Display license information.
-V, --version
Display version information.
-i, --input file
Input the credential from the specified file.
-n, --no-output
Discard all output.
-m, --metadata file
Output metadata to the specified file.
-o, --output file
Output the payload to the specified file.
-k, --keys string
Specify a subset of metadata keys to output. The keys are case-insensitive and delimited by whitespace, commas, semicolons, or periods -- as long as the string is treated as a single argument by the shell (e.g., enclosed by quotes). If a subset is not specified, all available keys are selected by default.
-K, --list-keys
Display a list of metadata keys.
-S, --socket path
Specify the local domain socket for connecting with munged.
The following metadata keys are supported.
|
STATUS |
The status of the credential decode operation. |
ENCODE_HOST
The address of the host on which the credential was encoded.
ENCODE_TIME
The time at which the credential was encoded (according to the clock of the host that encoded it).
DECODE_TIME
The time at which the credential was decoded (according to the local clock).
|
TTL |
The time-to-live value (in seconds) placed within the credential. | ||
|
CIPHER |
The cipher type used to encode the credential. | ||
|
MAC |
The MAC type used to encode the credential. | ||
|
ZIP |
The compression type used to encode the credential. | ||
|
UID |
The user ID of the process that encoded the credential. | ||
|
GID |
The group ID of the process that encoded the credential. |
UID_RESTRICTION
The user ID restriction placed within the credential.
GID_RESTRICTION
The group ID restriction placed within the credential.
|
LENGTH |
The length (in bytes) of the payload. |
The unmunge program returns an exit code corresponding to the return code of munge_decode(3). On success, it returns a zero exit code which signifies the credential is valid. On error, it prints an error message to stderr and returns a non-zero exit code.
