Understanding What Encryption Is
Encryption is a security method that turns readable information into coded data. Only someone with the correct key can turn it back into its original form.
How Encryption Works
When data is encrypted, it goes through a mathematical process that scrambles it. Anyone who intercepts the data sees only random characters unless they have the decryption key.
Why Encryption Is Important
Encryption protects sensitive information such as passwords, messages, banking data, and personal files. It keeps your information safe even if it is intercepted.
Where Encryption Is Used
It is used in messaging apps, websites, cloud storage, Wi-Fi networks, and digital payments. Encryption keeps online communication secure and private.
Types of Encryption
There are two main types: symmetric encryption, where one key is used to encrypt and decrypt, and asymmetric encryption, which uses a public and a private key.
The Simple Takeaway
Encryption turns readable data into secure code. It protects your information by ensuring only authorized people can access it.
