   • An encryption code or key is used to scramble the contents of data files
   • The proper code is needed to unscramble the file so it can be read and used
   • Data can be scrambled using encryption software when it is stored or transmitted between computers over networks
   • Digital signatures are used to check that a website or a message is authentic and are an example of encryption in use
