Class GeneratedKeyPairFactory

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

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 GeneratedKeyPairFactory
extends ProviderBasedFactory

Generates a new pair of a public and private keys. Note that as keys are not preserved across application context restarts, whatever you might have encrypted or signed using them will become invalid no later than when the JVM is shut down. Use the KeyStoreKeyPairFactory instead to load a persistent keypair from a Java keystore file.

GeneratedKeyPairFactory

public GeneratedKeyPairFactory()

Method Detail

setAlgorithm

public void setAlgorithm(java.lang.String algorithm)

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

Parameters:

algorithm - the key algorithm

setKeySize

public void setKeySize(int keySize)

Sets the size of the keys in bits. Defaults to 1024.

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

protected java.lang.Object createInstance()
                                   throws java.lang.Exception

Specified by:

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

Throws:

java.lang.Exception

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

Returns:

KeyPair.class
