What Is Encryption and How Does It Work?

Encryption is the process of encoding information in such a way that only authorized parties can understand it. In technical terms, it transforms plaintext into ciphertext using a mathematical algorithm and a secret key. Only users who possess the correct key can decrypt the ciphertext and return it to its original form.

There are two primary types of encryption used in modern systems: symmetric and asymmetric. Symmetric encryption uses a single key for both encryption and decryption. This method is fast and efficient but requires secure key distribution. Asymmetric encryption, by contrast, uses a pair of keys: a public key for encryption and a private key for decryption. This makes it more secure for transmitting data across insecure channels but generally slower than symmetric encryption.

Encryption algorithms have continued to advance. The Advanced Encryption Standard (AES), for instance, is widely adopted in government and industry and comes in 128-bit and 256-bit key lengths. The complexity of these keys makes brute-force attacks virtually impossible with current computing capabilities.
