Class ServletSignerFactory

java.lang.Object
  org.neuclear.commons.crypto.signers.ServletSignerFactory

public final class ServletSignerFactory
extends java.lang.Object

Used to create Signers from signers configuration parameters. It keeps a cache of Signers with similar parameters. Thus if you have several Servlets with the same keystore parameters they will use the same instance of Signer

The Configuration parameters are as follows:

parameter name	parameter value
keystore	The location of the JCE KeyStore. Defaults to the file .keystore in the users home directory If you specify test the built in Test keystore will be used.
serviceid	The main service ID of the service. Ie. neu://superbux.com/ecurrency. This is only required (and used) if you set keeppassphrase (see below)
passphraseagent	The type of passphraseagent to use. Valid options are signers, gui(default) and console
keeppassphrase	This asks for the service passphrase once at startup and remembers it through the lifetime of the signers

To use the factory. Do as follows within your servlets init() method: Signer signer=ServletSignerFactory.getInstance().createSigner(config);
