Top

  NameDescription
Public propertyKeySizeWhen overridden in a derived class, gets the size, in bits, of the key. (Inherited from SecurityKey.)

  NameDescription
Public methodDecryptKeyWhen overridden in a derived class, decrypts the specified encrypted key. (Inherited from SecurityKey.)
Public methodEncryptKeyWhen overridden in a derived class, encrypts the specified key. (Inherited from SecurityKey.)
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGenerateDerivedKeyWhen overridden in a derived class, generates a derived key using the specified cryptographic algorithm and parameters for the current key.
Public methodGetDecryptionTransformWhen overridden in a derived class, gets a transform that decrypts cipher text using the specified cryptographic algorithm.
Public methodGetEncryptionTransformWhen overridden in a derived class, gets a transform that encrypts XML using the specified cryptographic algorithm.
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetIVSizeWhen overridden in a derived class, gets the size, in bits, of the initialization vector (IV) that is required for the specified cryptographic algorithm.
Public methodGetKeyedHashAlgorithmWhen overridden in a derived class, gets an instance of the specified keyed hash algorithm.
Public methodGetSymmetricAlgorithmWhen overridden in a derived class, gets an instance of the specified symmetric algorithm.
Public methodGetSymmetricKeyWhen overridden in a derived class, gets the bytes that represent the symmetric key.
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodIsAsymmetricAlgorithmWhen overridden in a derived class, gets a value that indicates whether the specified algorithm uses asymmetric keys. (Inherited from SecurityKey.)
Public methodIsSupportedAlgorithmWhen overridden in a derived class, gets a value that indicates whether the specified algorithm is supported by this class. (Inherited from SecurityKey.)
Public methodIsSymmetricAlgorithmWhen overridden in a derived class, gets a value that indicates whether the specified algorithm uses symmetric keys. (Inherited from SecurityKey.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

Typically, this class is used by the infrastructure to transform XML using a symmetric key.
