A library of utilities related to payments, crypto, ISO8583 etc

UPDATE (03/22/2020)

There will be no further development on paysim, this repo will be strictly be used as a module/library
If you're interested in a ISO8583 simulator, please check out ISO WebSim

Folks developing on Windows please see this - https://github.com/rkbalgi/go/wiki/Building-on-Windows
Doesn't follow standard go style (coding conventions etc) - WIP
This has not be subject to any kind of targeted tests (performance or otherwise), so use this with a bit of caution - It's at the moment perhaps best suited for simulators

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)
