Add an option to hash collected files

[tclahr]

UAC does not copy collected files to destination folder (to save disk space and spend less CPU, IO and memory resources). Instead, UAC adds all paths to a text file and uses it as the source input file for tar and zip archives.

This is a very useful feature as the forensic analyst needs to show/prove the integrity of the collected files in some cases.

This option requires data to be previously copied to the destination directory before hashing. This also requires more disk space and CPU, IO and memory resources.
