Field Detail

encryptMode
String encryptMode(Code)

initialized
boolean initialized(Code)

ivCounter
protected static ByteArrayCounter ivCounter(Code)

randomGenerator
protected AbstractRandomNumber randomGenerator(Code)

stringEncryptor
protected AbstractStringEncryption stringEncryptor(Code)

stringHash
protected StringHash stringHash(Code)

strongCrypto
boolean strongCrypto(Code)
	Flag for string cryptography

Constructor Detail

CryptoManager
public CryptoManager()(Code)
	Do not call this constructor directly. Use getInstance() instead. This is public ONLY so that it can be instantiated by the test program.

Method Detail

configure
public synchronized void configure(Configuration newConfig) throws ConfigurationException(Code)
	Configure the Cryptographic manager Parameters: newConfig - the new configuration bean to configure with throws: ConfigurationException - upon configuration error

destroy
public synchronized void destroy()(Code)
	Method removes all static entries.

getCryptoKey
public String getCryptoKey()(Code)

getEncryptMode
public synchronized String getEncryptMode()(Code)

getInstance
public static synchronized CryptoManager getInstance() throws ChainedException(Code)
	Singleton Generator. Call to get an instance of the Crypto Manager Please Note If strong encryption is used, this class may take quite some time in initializing due to the nature of generating a default seed for the crypto-strength random number generator. the ony and only instance of the Crypto Manager; throws: ChainedException - If there is a problem instantiating the crypto classes

getRandomGenerator
public synchronized AbstractRandomNumber getRandomGenerator()(Code)
	Returns an instantiated subclass of AbstractRandomNumber depending if strong or weak crypto is desired. a random number generator See Also: com.jcorporate.expresso.core.security.AbstractRandomNumber See Also: com.jcorporate.expresso.core.security.weakencryption.RandomNumber See Also: com.jcorporate.expresso.core.security.strongencryption.RandomNumber

getRandomSeed
public String getRandomSeed()(Code)

getStringEncryption
public synchronized AbstractStringEncryption getStringEncryption()(Code)
	Factory method that returns an instantiated subclass of `AbstractStringEncryption` depending of strong or weak crypto is desired. A string encryption concrete class. See Also: com.jcorporate.expresso.core.security.AbstractStringEncryption See Also: com.jcorporate.expresso.core.security.weakencryption.StringEncryption See Also: com.jcorporate.expresso.core.security.strongencryption.StringEncryption

getStringHash
public synchronized StringHash getStringHash()(Code)
	Factory method that returns an instantiated subclass of `AbstractStringHash` depending of strong or weak crypto is desired. An instantiated String Hashing class See Also: com.jcorporate.expresso.core.security.StringHash

initialize
public synchronized void initialize()(Code)

isInitialized
public boolean isInitialized()(Code)

isStrongCrypto
public synchronized boolean isStrongCrypto()(Code)

isUsingStrongCrypto
public synchronized boolean isUsingStrongCrypto()(Code)
	Returns whether the crypto manager is using strong cryptography or not. true if a strong cryptographic provider is included

loadClasses
public synchronized void loadClasses(boolean useStrongCrypto) throws ChainedException(Code)
	Loads the appropriate crypto classes. Also is split off from the constructor for testing purposes. Parameters: useStrongCrypto - Set to true if we desire to load the strongcryptographic classes. throws: ChainedException - upon error loading the classes.

reconfigure
public synchronized void reconfigure(Configuration newConfig) throws ConfigurationException(Code)
	Reconfigure lifecycle event. Destroys itself and reconstructs with the new configuration Parameters: newConfig - the configuration data to reconfigure with.
