WebSymmetric cryptography - Alice and Bob know the same key and use it for encryption and decryption. Symmetric crypto can be used to ensure secrecy - Alice and Bob exchange the secret key and use it to communicate privately. It can also be used for secure storage - Alice encrypts the files she stores in the cloud. If the cloud is compromised no ... WebThe most common type of cryptography key is a symmetric key, which uses the same key to encrypt and decrypt data -- as opposed to asymmetric keys, which use a separate key for encryption and decryption. Generated using a symmetric algorithm, sessions keys have number of advantages: The major advantage of session keys is they are convenient to use.
