Symmetric-key cryptosystems use the same key for encryption and decryption of a message, although a message or group of messages can have a different key than others. A significant disadvantage of symmetric ciphers is the key management necessary to use them securely. Each distinct pair of communicating parties must, ideally, share a different ... ENCRYPTION IS A PART of almost every service or device we use to live our lives online. Every day, often without us even being aware of it, encryption keeps our personal data private and secure.
