What is data encryption?

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.
