Method Detail

getInstance

public static Crypto getInstance()
                          throws WSSecurityException

getInstance

Returns an instance of Crypto. This method uses the file crypto.properties to determine which implementation to use. Thus the property org.apache.wss4j.crypto.provider must define the classname of the Crypto implementation. The file may contain other property definitions as well. These properties are handed over to the Crypto implementation. The file crypto.properties is loaded with the Loader.getResource() method.

Returns:

The crypto implementation was defined

Throws:

WSSecurityException - if there is an error in loading the crypto properties

getInstance

public static Crypto getInstance(Properties properties)
                          throws WSSecurityException

getInstance

Returns an instance of Crypto. The properties are handed over the the crypto implementation. The properties must at least contain the Crypto implementation class name as the value of the property : org.apache.wss4j.crypto.provider

Parameters:

properties - The Properties that are forwarded to the crypto implementation and the Crypto impl class name. These properties are dependent on the crypto implementation

Returns:

The cyrpto implementation or null if no cryptoClassName was defined

Throws:

WSSecurityException - if there is an error in loading the crypto properties

getInstance

public static Crypto getInstance(Properties properties,
                                 ClassLoader classLoader,
                                 PasswordEncryptor passwordEncryptor)
                          throws WSSecurityException

getInstance

Returns an instance of Crypto loaded with the given classloader. The properties are handed over the the crypto implementation. The properties must at least contain the Crypto implementation class name as the value of the property : org.apache.wss4j.crypto.provider

Parameters:

properties - The Properties that are forwarded to the crypto implementation and the Crypto impl class name. These properties are dependent on the crypto implementation

classLoader - The class loader to use

passwordEncryptor - The PasswordEncryptor to use to decrypt encrypted passwords

Returns:

The crypto implementation or null if no cryptoClassName was defined

Throws:

WSSecurityException - if there is an error in loading the crypto properties

getInstance

public static Crypto getInstance(Class<? extends Crypto> cryptoClass,
                                 Map<Object,Object> map)
                          throws WSSecurityException

getInstance

Returns an instance of Crypto. The supplied map is handed over the the crypto implementation. The map can be null. It is dependent on the Crypto implementation how the initialization is done in this case.

Parameters:

cryptoClass - This is the crypto implementation class. No default is provided here.

map - The Maps that is forwarded to the crypto implementation. These contents of the map are dependent on the underlying crypto implementation specified in the cryptoClassName parameter.

Returns:

The crypto implementation or null if no cryptoClassName was defined

Throws:

WSSecurityException - if there is an error in loading the crypto properties

getInstance

public static Crypto getInstance(String propFilename)
                          throws WSSecurityException

getInstance

Returns an instance of Crypto. This method uses the specified filename to load a property file. This file shall use the property org.apache.wss4j.crypto.provider to define the classname of the Crypto implementation. The file may contain other property definitions as well. These properties are handed over to the Crypto implementation. The specified file is loaded with the Loader.getResource() method.

Parameters:

propFilename - The name of the property file to load

Returns:

The crypto implementation that was defined

Throws:

WSSecurityException - if there is an error in loading the crypto properties

getInstance

public static Crypto getInstance(String propFilename,
                                 ClassLoader customClassLoader)
                          throws WSSecurityException

Throws:

WSSecurityException

getProperties

public static Properties getProperties(String propFilename,
                                       ClassLoader loader)
                                throws WSSecurityException

This allows loading the resources with a custom class loader

Parameters:

propFilename -

loader -

Returns:

a Properties object loaded from the propFilename argument

Throws:

WSSecurityException - if there is an error in loading the crypto properties
