Java Security, 2nd Edition

Name

Class javax.crypto.ExemptionMechanism

Synopsis

This class can be used by implementors of a JCE package to provide hooks into the exemption mechanisms of various governments. This is done in order to satisfy the import and/or export restrictions of those governments, who might require (for example) a key escrow implemented with this class. It is not used by Sun’s implementation of JCE.
