## notes:
## this script will decrypt files encrypted with encrypt-files.sh, provided you have 
## put the same thekey.key file the previous script generated back into the direcotry
## containing your encrypted files.
## the ownders of this website take no responsibility for errors or loss of data stemming 
## from the use of either encrypt-data.sh or decrypt-data.sh
## THEREFORE you should experiment and learn how to use them before committing 
## vital data to  these procdedures.  Keep in mind that you will require the requisite imported
## libraries for the scripts to function.
