TheImportanceofEncryption
Encryptionplaysavitalroleinprotectingsensitiveinformationfromcyberthreatssuchashacking,identitytheft,anddatabreaches.Financialinstitutions,governmentagencies,andbusinessesuseencryptiontoprotecttheconfidentialityoftransactions,communications,andpersonaldata.Forexample,creditcardcompaniesuseencryptiontoprotectcustomers'cardnumbersduringtransactions.
Encryptionalsohelpssecurecommunicationchannelssuchasemailandinstantmessaging.End-to-endencryption,inwhichthemessageisencryptedanddecryptedonlybythesenderandreceiver,ensuresthatonlytheintendedrecipientcanreadthemessage.Thisisparticularlyimportantforindividualsandorganizationsthatdealwithsensitiveinformation,suchasdoctorsandlawyers.
