[rabbitmq-discuss] AMQP, RabbitMQ and message integrity

[James Gardner]

I would appreciate some information on whether there are any guarantees 
or safeguards in RabbitMQ against message corruption along the 
publisher->rabbitmq->consumer chain.
Perhaps that question can largely be rephrased as what guarantees does 
*AMQP* make about message integrity, although how messages are stored 
and transported within RabbitMQ would surely be a part of it too.

One reason I am trying to get a feel for this is to figure out whether 
the publisher needs to include a message body hash (eg. MD5) in the 
header, so that a receiver can check it, or whether that would be 
redundant. The concern would be about corruption due to technical 
phenomena rather than malice, ie. I'm not coming at this from a security 
perspective.
The topology in question would include federation links across a WAN as 
well as LAN.
I haven't seen this issue addressed anywhere in the docs but if I missed 
it I would be grateful if you could point me to it.
Many thanks,
