The Secure Stomp Messenger (SSM) is a python package designed to send arbitrary files using ActiveMQ and the STOMP protocol. Its key features are:
- It uses the underlying filesystem to store outgoing and / or incoming messages
- It sends arbitrary files from a client to a server SSM
- It can use any broker configured to use STOMP
- Files are signed and may be encrypted during transit using X509 certificates
The SSM is designed to have a simple interface, which isolates it from any other components it may be used with.
Very simplified version
- The sending and receiving SSMs are configured to communicate using a specified queue.
- A file is written to the sending SSM's 'outgoing' directory (by some other process) - see APEL/SSM2AddingFiles.
- The file disappears from outgoing directory when
- The file appears in receiving SSM's 'incoming' directory if <ssmreceive> is running.
Once the sending and receiving SSMs are configured and running correctly, to send a message, put a file in the correct outgoing directory with the correct name and it will disappear. It will arrive in the incoming directory of the receiving SSM.
