public final class IpSecTransform
extends Object implements AutoCloseable


This class represents a transform, which roughly corresponds to an IPsec Security Association.

Transforms are created using IpSecTransform.Builder. Each IpSecTransform object encapsulates the properties and state of an IPsec security association. That includes, but is not limited to, algorithm choice, key material, and allocated system resources.

Public methods

Deactivate this IpSecTransform and free allocated resources.

Inherited methods

From class java.lang.Object
From interface java.lang.AutoCloseable

Public methods


void close ()

Deactivate this IpSecTransform and free allocated resources.

Deactivating a transform while it is still applied to a socket will result in errors on that socket. Make sure to remove transforms by calling removeTransportModeTransforms(FileDescriptor). Note, removing an IpSecTransform from a socket will not deactivate it (because one transform may be applied to multiple sockets).

It is safe to call this method on a transform that has already been deactivated.

Protected methods


void finalize ()

Check that the transform was closed properly.
