The ciphertext can then be decrypted back into its original form by those who possess the appropriate decryption key. Encryption is widely used in various applications, including online communication, financial transactions, and data storage __82__ it provides a layer of protection against unauthorized access and interception. One __83__ encryption method is the Advanced Encryption Standard (AES), which is widely regarded as a secure and efficient algorithm. AES operates on blocks of data and utilizes a symmetric key approach, __84__ the same key is employed for both encryption and decryption. __85__ encryption technique is asymmetric encryption, which uses a pair of keys: a public key and a private key. The public key is used for encryption, while the private key is kept secret and used for decryption.
