Kryptografie - nauka o metodách utajování smyslu zpráv převodem do podoby čitelné pouze se speciální znalostí. Slovo kryptografie pochází z řečtiny – kryptós znamená skrytý a gráphein je psát. Steganografie - věda zabývající se utajením komunikace prostřednictvím ukrytí zprávy. Kryptografie, známější pod pojmem šifrování, je nauka o utajení zpráv. Zprávy jsou zašifrovány podle různých druhů algoritmu tak, aby vstupní text převedli do šifrované verze. Zároveň zašifruje tak, aby dešifrování bylo co nejsložitější, nebo se na první pohled zdálo složité.
