I was giving a try on the script by passing it any folder string, i.e: c:\I\wonder\what\its\used\for\
In the end it seems to split the drive name 'C:' from the
path '\I\wonder\what\its\used\for\' and takes this for doing
grabing some of the hex values in @xlat and convert hex->Ascii and creates a string, which will be printed.
Possible usage is to encrypt pathnames or to encrypt anything else you can provide on the command line to the script.
However, the line hex(substr($e,$i,2))^$xlat[$s++]
is taking a substring and does a binary XOR with the hex value - selected by $s which will be postincremeted. So to me it looks like simple encrypting text..
But I am just guessing!
