Encryption: The Art of Keeping Secrets

Encryption is the process of converting data into a form that cannot be read without a special key. This makes it a valuable tool for protecting sensitive information, such as passwords, credit card numbers, and medical records. There are two main types of encryption: symmetric encryption and asymmetric encryption. Symmetric encryption uses the same key to encrypt and decrypt data. This makes it relatively fast and efficient, but it also means that anyone who knows the key can decrypt the data.
