Class GeneratedSecretKeyFactory

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

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 GeneratedSecretKeyFactory
extends ProviderBasedFactory

Generates a new secret key. Note that as the key is not preserved across application context restarts, whatever you might have encrypted using it will become invalid no later than when the JVM is shut down.

public GeneratedSecretKeyFactory()

Method Detail

setAlgorithm

public void setAlgorithm(java.lang.String algorithm)

Sets the key algorithm to use. Defaults to "AES".

Parameters:

algorithm - the key algorithm

setKeySize

public void setKeySize(int keySize)

Sets the size of the keys in bits. Defaults to 128.

Parameters:

keySize - the size of the keys.

setSecureRandom

public void setSecureRandom(java.security.SecureRandom secureRandom)

Sets an instance of secure random to use. If not set, a one-off instance created using a private instance of SecureRandomFactory will be created, with the configured security provider.

Parameters:

secureRandom - the secure random instance to use.

createInstance

getObjectType

public java.lang.Class getObjectType()

Specified by:

getObjectType in interface org.springframework.beans.factory.FactoryBean

Specified by:

getObjectType in class org.springframework.beans.factory.config.AbstractFactoryBean
