In cryptography, encryption is the process of encoding information. This process converts the original representation of the information, known as plaintext, into an alternative form known as ciphertext. Ideally, only authorized parties can decipher a ciphertext back to plaintext and access the original information.

What does it mean when something is encrypted?

Data encryption is a security method where information is encoded and can only be accessed or decrypted by a user with the correct encryption key. Encrypted data, also known as ciphertext, appears scrambled or unreadable to a person or entity accessing without permission.

Is encrypted good or bad?

Consider its role: Encryption helps keep you safe while doing things like browsing the Web, shopping online, and reading email on your computer or mobile device. It's critical to computer security, helps to protect data and systems, and helps to protect you against identity theft.
