What is the role of encryption in data security?

What is the role of encryption in data security?

Encryption is a process that converts data into a coded format, making it unreadable without a decryption key. It protects sensitive information from unauthorized access.

Can you give me examples of where encryption is used?

Sure! Encryption is commonly used in online banking, email communication, and secure file storage to protect personal and financial information.

How does encryption work in practice?

In practice, encryption uses algorithms to transform plaintext into ciphertext. Only those with the correct key can decrypt it back to plaintext.

What are the different types of encryption?

There are two main types: symmetric encryption, where the same key is used for both encryption and decryption, and asymmetric encryption, which uses a pair of keys.

Is encryption foolproof?

While encryption significantly enhances security, it's not foolproof. Vulnerabilities can exist in the implementation, and keys can be compromised.
