Class KeySpecSecretKeyFactory

java.lang.Object
  org.springframework.beans.factory.config.AbstractFactoryBean
      org.szegedi.spring.crypto.support.ProviderBasedFactory
          org.szegedi.spring.crypto.KeySpecSecretKeyFactory

All Implemented Interfaces:

org.springframework.beans.factory.BeanFactoryAware, org.springframework.beans.factory.DisposableBean, org.springframework.beans.factory.FactoryBean, org.springframework.beans.factory.InitializingBean

public class KeySpecSecretKeyFactory
extends ProviderBasedFactory

Generates a secret key from an implementation-independent secret key specification. Tipically, you can construct such a specification in memory, or load it from a serialized file, or synthesize it from a password. Equal specifications result in identical keys, thus you can use it to construct a key valid accross JVM restarts.
