Data encryption is the act of changing electronic information into an unreadable state by using algorithms or ciphers. Originally, data encryption was used for passing government and military information electronically. Over time as the public has begun to enter and transmit personal, sensitive information over the internet, data encryption has become more widespread. Nowadays Web Browsers will automatically encrypt text when connecting to a secure server. You can tell you are on a secure, encrypted website when the URL begins with "https", meaning Hypertext Transmission Protocol, Secure.

The Internet Protocol Security (IPsec) protocol that provides confidentiality by encrypting data is the Encapsulating Security Payload (ESP). ESP ensures data confidentiality through encryption while also providing authentication and integrity for the transmitted data. It is commonly used in virtual private networks (VPNs) to secure communication over untrusted networks.
