Client side

The client consists of sending a message and retrieving messages clients have sent to it.

Before that, create the client stub from the WDSL:

• fglwsdl -domHandler myservice.wsdl

The client stub reference handlers:

• SecureMessageBox_HandleRequest

• SecureMessageBox_HandleResponse

• SecureMessageBox_HandleResponseFault

For more details about client SOAP handlers see Client stub and handlers.

What to do when a message is sent:

• Sign and encrypt the request for the server (WS-Security)

  • sign with client private key

  • encrypt with server public key

• Send key information in the request

  • key to identify the sender/client

  • key to identify the recipient/server

  • key used to encrypt the data (usually a symmetric key encrypted by the recipient public key)

• If the message has to be encrypted for the final recipient (XML-Security)

  • sign the message

  • encrypt the message

What to do to retrieve messages:

• Identify the sender and validate the sender (search in keystore)

• Identify the recipient (should be the server itself)

• Decrypt the request

• Check the signature

• Retrieve messages for the recipient
