class NetSSL_API PrivateKeyPassphraseHandler
	/// A passphrase handler is needed whenever the private key of a certificate is loaded and the certificate is protected
	/// by a passphrase. The PrivateKeyPassphraseHandler's task is to provide that passphrase.
	/// One can install one's own PrivateKeyPassphraseHandler by implementing this interface. Note that
	/// in the implementation file of the subclass the following code must be present (assuming you use the namespace My_API 
	/// and the name of your handler class is MyGuiHandler):
	///    
	///    #include "Poco/Net/PrivateKeyFactory.h"
	///    ...
	///    POCO_REGISTER_KEYFACTORY(My_API, MyGuiHandler)
	///
	/// One can either set the handler directly in the startup code of the main method of ones application by calling
	///
	///    SSLManager::instance().initialize(myguiHandler, myInvalidCertificateHandler, mySSLContext)
	///
	/// or in case one's application extends Poco::Util::Application one can use an XML configuration and put the following entry
	/// under the path openSSL.privateKeyPassphraseHandler:
	///    
	///    <privateKeyPassphraseHandler>
	///        <name>MyGuiHandler</name>
	///        <options>
	///            [...] // Put optional config params for the handler here
	///        </options>
	///    </privateKeyPassphraseHandler>
	///
	/// Note that the name of the passphrase handler must be same as the one provided to the POCO_REGISTER_KEYFACTORY macro.
