unmunge — MUNGE credential decoder
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 and 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.
The status of the credential decode operation.
The address of the host on which the credential was encoded.
The time at which the credential was encoded (according to the local clock of the host that encoded it).
The time at which the credential was decoded (according to the local clock of the host that decoded it).
The time-to-live value (in seconds) placed within the credential.
The cipher type used to encode the credential.
The MAC type used to encode the credential.
The compression type used to encode the credential.
The user ID of the process that encoded the credential.
The group ID of the process that encoded the credential.
The user ID restriction placed within the credential.
The group ID restriction placed within the credential.
The length (in bytes) of the payload.
The unmunge program returns an exit code corresponding to the return code of munge_decode(). 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.
