We want a simple app that will run under Windows (7 or higher) that can search hard drives for key words, and replace them with (say) 16-character hashes. We will place a CSV of the key words (about 10,000) on the drive of the PC alongside the app. The subject drive will be connected to the PC in an external caddy via USB. Each subject drive may have hundreds of instances of words that are on the CSV list and must be hashed. The words may appear in file OR folder names. The app must be recursive to find all instances no matter how many levels deep they are. The hash must conform to Windows file and folder naming protocols. The process should be reversible in the future by entering a master hash in the app.
