This security_checksums_objects.cfg example specifies MD5 checksums and file sizes for use by the ChecksumDifferenceCritical script, which uses this information to report unexpected checksum and/or file size changes, perhaps indicative of hacker activity. Note how the #include directives incorporate several different sets of checksums, for example checksums_piktbin_objects.cfg and checksums_suse_linux_objects.cfg.

On the piktmaster system, we would install the Checksums.obj file to each PIKT slave system with the command:
# piktc -iv +O Checksums +H all [or: ... -H downsys]
