When I worked for BofA decades ago, there was a PDP-11 at the center of a point to point network of other machines for handling SWIFT, Telex, FedWire .... This network turned over the assets of the bank every 4 days and BofA at the time was the largest private bank in the world. The password for that console was sesame. Transactions were testworded but otherwise sent in plain text. When I worked in Europe a few years later I constructed by own telex bankwire transaction from a hotel in Italy. It was to my account for my money but it worked, no questions asked.
