+ This method is called by the public `Dispose()` method and the `Finalize` method. `Dispose()` invokes the protected `Dispose(Boolean)` method with the `disposing` parameter set to `true`. `Finalize` invokes `Dispose` with `disposing` set to `false`.
+
+ When the `disposing` parameter is `true`, this method releases all resources held by any managed objects that this <xref:System.Security.Cryptography.SymmetricAlgorithm> references. This method invokes the `Dispose()` method of each referenced object.
