You’ve probably heard about data encryption before, but if you still aren’t exactly sure what it is, here’s the scoop on data encryption:
The purpose of data encryption is to protect digital data confidentiality. Data encryption uses an algorithm, which translates the data into another form or code. Without a secret encryption key, this data is unreadable.
Encryption is one of the most widely used and effective data security methods used by organizations to transfer data.
Examples
• When you use your credit card online, your computer encrypts that information so that others can’t steal your personal data as it is being transferred.
• When you see the 
image, it means that there is an encrypted link between the website’s server and your browser.
