A library of utilities related to ISO message processing

Paysim

An open ISO8583 Simulator

• The application is built using go and GTK+2 bindings made available at github.com/mattn/go-gtk (Thanks a ton Yashuhiro Matsumoto!)
• The entire source code is available at https://github.com/rkbalgi/go
• The interesting packages would be github.com/rkbalgi/go/execs/paysim, github.com/rkbalgi/go/paysim and github.com/rkbalgi/iso8583
• There are loads of other interesting things available in other packages – like a minimalist implementation of a Thales HSM for basic commands (A6, MS, M6 and the like)
