5.2.3 Encrypted Data
Yet. another. way. that. data. might. be. made. hard. or. impos-
sible.to.access.is.through.encryption.(Figure 5.3)..There.are.
many.ways.to.encrypt.data.on.a.computer,.from.the.relatively.
simple.act.of.assigning.a.password.to.a.ile,.to.the.incredibly.
complex.process.and.management.of.digital.certiicates.that.
automatically. encrypt. data. in. e-mails,. or.speciic. folders,. or.
even.entire.hard.drives.
On.newer.Windows.operating.systems,.they.include.a.tool.
called.BitLocker..This.allows.you.to.create.speciic.encrypted.
folders.such.that.any.data.that.you.want.to.protect.can.simply.
be. stored. in. those. folders. and. a. pass. phrase. is. required. to.
access.the.data.
