Basically I am trying to do the following. Imagine some messages are being exchanged between two users.At each endpoint information is stored based on the messages. Now in order to access this information I want to create a key or a hash based on some content that is common to all the messages that are exchanged eg. address, name, phone number etc. What do you think I could use for this case?
All help appreciated!!
Cheers,
Valerie
