Java Security, 2nd Edition

Name

Class javax.crypto.CipherSpi

Synopsis

This class is the service provider interface of the Cipher class. To implement a particular cipher algorithm, create a subclass of this class and register the class with an appropriate security provider. Like all SPI classes, the methods that begin with engine are called by their corresponding method (without engine) from the Cipher class. This is a JCE engine, which means it must be deployed in a specially signed jar file.
