Currently, when you try to export the B2B assets or Integration workflows, they are in some encrypted format which is not easy to understand.
Often times, there is a need to create innovative solutions, accelerators to expediate migration projects, do analysis of workflows to ensure quick wins etc.
It would be nice if the exported assets use the standard formats such as JSON, XML, RAML etc that are easy to understand, to propels innovation and facilitate faster solution development.
It’s been a while since I worked with the B2B side of webMethods, but are you sure they are encrypted and not zipped? Try adding a .zip extension and seeing if you can open it. I vaguely recall doing that with exported assets from Trading Networks years ago.
