AqBanking is a modular and generic interface to online banking tasks, financial file formats (import/export), and bank/country/currency information. AqBanking uses backend plugins to actually perform the online tasks. HBCI, OFX DirectConnect, and EBICS are currently supported. AqBanking is used by GnuCash, KMyMoney, Pecunia, AqBanking-CLI, and QBankManager.
AqFinance is the successor to QBankManager. It is a graphical accounting application based on double-entry accounting. The GUI uses the FOX toolkit. The package contains AqFinance (the GUI application), AqFinance-CLI (a command line tool to manipulate and export the AqFinance database), and AqBanking-CLI (a command line tool for online banking tasks). It supports all online banking protocols provided by AqBanking (currently HBCI and OFX DirectConnect). A version supporting EBICS (a German online banking protocol) is also available. AqFinance contains the latest versions of AqBanking, Gwenhywfar, and Libchipcard.
AqMail fetches mails from remote mailboxes (POP3), applies admin-defined filters, and stores the email in local mailboxes for POP3 daemons to serve them. It supports virtual mail domains and users. It has been tested with QMail as the MTA and with Spamassassin and ClamAV as filters.
Gwenhywfar is a multi-purpose library that provides useful functions such as configuration file handling, a full featured message generation and parsing engine, and an operating system abstraction layer. It is used by Libchipcard2, AqBanking, QBankManager, OpenHBCI, AqMoney, and various other projects.
openHBCI is a C++ library for the German HomeBanking Computer Interface. It includes some tutorials for testing the library. Its current capabilities include complete key management on disc (RDH) and/or chip-card (DDV), the ability to perform single customer credit transfers, and the ability to get balance reports.
PC/SC-Proxy allows for access to PC/SC daemons on remote machines. There are two use cases. It can be used with thin clients and a terminal server to make the session access readers connected to the thin client. In this case, the address of the remote PC/SC service is taken from the login information (utmp). The second use case is when applications running inside a virtual machine (e.g. VirtualBox) need access to card readers of the host machine without disturbing operations on the host itself.
