SymmetricKey

SymmetricKey[assoc]

represents all the information needed for encryption, decryption, and other operations in a symmetric cryptographic system.

Details

  • SymmetricKey objects can be used with functions such as Encrypt and Decrypt.
  • A single SymmetricKey object can be used for both encryption and decryption.
  • SymmetricKey[…]["prop"] yields properties of the symmetric key. Possible properties include:
  • "Cipher"cipher used
    "Key"key as a ByteArray
    "KeySize"size of key in bits
  • Possible methods are as listed for GenerateSymmetricKey.
  • SymmetricKey[…]["Parameters"] gives all the information contained in the object, as an association.
  • SymmetricKey[…]["Properties"]
    • gives a list of available properties.

Examples
