DerivedKey

DerivedKey[assoc]

represents a derived key generated by GenerateDerivedKey.

Details

  • DerivedKey is an object containing a secure key, which can be used in place of a plain-text password.
  • DerivedKey contains all the information necessary to verify the password used to generate the key.
  • In DerivedKey[assoc], the association assoc contains the following:
  • "Function"key derivation function used
    "FunctionParameters"arguments of the key derivation function
    "DerivedKey"derived key
    "Salt"salt used to derive the key
  • The value of "FunctionParameters" is an Association that contains "KeySize" and parameters specific to the key derivation function used.
  • DerivedKey[assoc]["prop"] gives the specified element of assoc; it is equivalent to assoc["prop"].
  • DerivedKey[assoc]["PHCString"] gives a string representation of the derived key.
  • DerivedKey[assoc]["KeySize"] gives the size of the key in bits.
  • DerivedKey[assoc]["Parameters"] gives all the information contained in the object, as an association.
  • DerivedKey[assoc]["Properties"] gives a list of available properties.
