pbsum prints the checksum of one or more files. The checksum can be used in a policy configuration file to check the requested program’s integrity. If anyone has modified the program and thereby changes the checksum, the secured task is refused. The string that is produced by pbsum can be used to set the value of the runmd5sum variable in the Privilege Management for Unix and Linux policy configuration file.
