Kulesi sikhathi sedijithali, ukuvikela nokubethela (encrypting) idatha yomuntu siqu sekuvele kubalulekile ekuvikeleni ubumfihlo nokuphepha. Ngokwanda kokuhlaselwa okuvela ku-inthanethi (cyber threats), okufana nokugqekeza (hacking), ukwebiwa kobunikazi (identity theft), nokuqagela okungagunyaziwe (unauthorized surveillance), imininingwane ebucayi njengemininingwane yezimali, amagama ayimfihlo (passwords), nemiyalezo yangasese ingagcina isiwela ezandleni ezingalungile kalula.
Isebenza lokubhaliwe njengendlela yokuzivikela enamandla, iguqula idatha ibe yikhodi engafundeki engakwazi ukufinyelelwa kuphela ngabantu abagunyaziwe abane-ukhiye ofanele wokuyibuyisela emuva (decryption key). Lokhu kuqinisekisa ukuthi noma ngabe idatha ibanjwe (intercepted), ihlala ivikelekile futhi iyimfihlo. Ngenhlanhla, kunamathuluzi amaningi enziwe ngemithombo evulekile (open-source) namahhala akwenza kube lula ukuthi noma ubani avikele idatha yakhe ngaphandle kokuphazamisa ikhwalithi noma ukuphepha—ngaphandle uma abasebenzisi benginquma okunye.
