Encryption is essential for protecting private information as it travels through the web. It disguises sensitive data as random gibberish, ensuring that only intended recipients can access the information. Encryption forms the foundation of trust on the internet, with 95% of Google's traffic being encrypted. It assures users that the websites they visit have not been intercepted and that their private information remains confidential. However, the evolution of electronic transactions and the abstract nature of money have made encryption an indispensable tool for safeguarding sensitive financial and personal data.
