Class IXSILInit

java.lang.Object

iaik.ixsil.init.IXSILInit

public class IXSILInit
extends java.lang.Object

Encapsulates all issues regarding the initialization of IXSIL.

• Specify the IXSIL init properties file, which contains the default values for the basic initialization of IXSIL.
  
• Change values of the IXSIL init properties.
  
• Change values of the IXSIL algorithm properties.
  
• Change values of the IXSIL keymanager properties.

The initialization properties are organized in three property files:

• The basic initialization properties are grouped in the IXSIL init properties file. The location of this file must be specified using the init(iaik.ixsil.util.URI) method of this class.
  
• One basic initialization property contains the location of the file containing the IXSIL algorithm properties. Each of these properties holds an association between an algorithm URI as specified by the XML Signature standard and the class file implementing this algorithm conforming with the IXSIL Algorithm interface.
  
• Another basic initialization property contains the location of the file containing the IXSIL keymanager properties. These properties manages the associations between the kinds of keying information provided by an XML signature, and the corresponding implementation classes for those keying information.

Method Detail

init

public static void init(URI initPropertiesLocation)
                 throws InitException

Initializes IXSIL API with values provided by the specified IXSIL init properties file.

Parameters:

initPropertiesLocation - An URI specifying the IXSIL init properties file. If a relative URI is specified, i. e. if there is no scheme part, then the properties file is searched in the class path.

Throws:

InitException - if the IXSIL init properties cannot be read.

                 throws InitException

An alternative way for initializing the IXSIL API. init, algoritm and keyManager properties are passed to IXSIL as Properties objects. Please note: The property named location.initProperties must be set in the IXSIL init properties, if this method is used to initialize the library. See the inline documentation in the example IXSIL init properties file that is shipped with IXSIL for further information.

Parameters:

initProperties - The IXSIL init properties. Must not be null.

algorithmProperties - The IXSIL algorithms properties. Must not be null.
