We have actually a “Invoicing System” developed in Powerbuilder, now laws in my country changed and we need implement an “Electroning invoicing” interfase to our system, for that is necessary to have a process to convert invoces to XML UBL format and create a hash to encrypt and sign digitally this document using a digital certificate with a private and public keys.
Then,,,,,,, the project is to create an API or any process (can be in C++, java or other) that generate the hash and the digital signature for the xml created for the system, the APi or process must be compatible to add or can interact with our system in power builder (we can do the process to communicate with the API)
