encryption
en-KRIP-shuhn
/ɪnˈkrɪpʃən/
The process of encoding digital data into an unreadable scrambled format to prevent unauthorized access.
Essential for online banking, private messaging, and secure Wi-Fi protocols (such as WPA3).
The story behind the word. Traced to the ancient Greek 'kryptos', meaning hidden or secret (which also gave us crypt and tomb). The modern prefix 'en-' was attached in the 20th century to designate the technical process of hiding readable information inside secure mathematical codes.
