Encryption
The process of converting readable data into an unreadable format using mathematical algorithms, ensuring only authorised parties with the correct key can access it.
Encryption scrambles your data so that even if someone intercepts it, they cannot read it without the decryption key. It is fundamental to online banking, messaging apps (WhatsApp end-to-end encryption), HTTPS websites, and any system handling sensitive information. Under Malaysia's PDPA, encryption is a recommended security measure for protecting personal data.
