Data integrity

 

A message can be digitally signed by an API exit when the message is put by the sending application. The digital signature can then be checked by a second API exit when the message is retrieved by the receiving application. This can detect whether the message has been deliberately modified.

As discussed in Data integrity, some protection can be provided by using a message digest instead of a digital signature.
