It's a library to handle SET messages, build on top of openssl crypto and ASN.1. Available is source, messages captured and screenshots. It was used to build a merchant (an apache module) capable to accept a signed order from IBM Wallet. All certificates were also generated with this library. your comments are welcome, Vadim Fedukovich
