history

Project history and usage

KtoBLZCheck is a C/C++ library and set of command-line tools for checking German and other bank account numbers, bank codes, and IBANs. Its documentation explains the name as a combination of Konto, the German abbreviation for account number, and BLZ, the German bank-code abbreviation.

Project history

The SourceForge project was registered on 2002-08-17, making it a long-running finance-oriented open source library from the SourceForge era. The project page describes it as based on Deutsche Bundesbank specifications for German bank codes.

The Doxygen documentation identifies Fabian Kaiser as the original author, with Christian Stimming and Alexander Kurz listed as maintainers. Over time the package grew beyond a single checker into a library, CLI tools, IBAN checking, Python bindings, CMake build support, and conversion of Bundesbank bank-data files into ktoblzcheck's compact runtime format.

Adoption history

KtoBLZCheck's adoption is strongest in accounting, finance, and personal-finance software stacks that need offline validation of German account identifiers. Its packaging across Homebrew, MacPorts, Linux distributions, and SourceForge tarballs reflects a stable library dependency rather than a fashionable end-user CLI.

The project also exposed web checkers for bank accounts and IBANs, and the documentation names related bindings and implementations such as rbktoblzcheck and konto_check.

How it is used

The package provides the `ktoblzcheck`, `ibanchk`, and `ktoblzupdate` executables. The documented CLI checks a bank-code/account-number pair, can emit single-line tab-delimited output for batch processing, and uses bank-data files derived from Deutsche Bundesbank BLZ data.

Why package nerds care

KtoBLZCheck is package-nerd interesting because it is code plus regulated reference data. Releases are not just API changes; they also track bank-data validity periods, Bundesbank source-file changes, and build-system support for downstream distributors.

Timeline

  • 2002-08-17: KtoBLZCheck registered on SourceForge.
  • 2007-11-07: ktoblzcheck 1.16 release appeared in the SourceForge file feed and introduced the documented multiple-validity-period bank-data behavior.
  • 2017-03-02: SourceForge file listing identified ktoblzcheck-1.49.tar.gz as the download-page version.
  • 2025-05-20: SourceForge code feed recorded the commit titled Release version 1.59.

Related projects

  • KtoBLZCheck is tied to Deutsche Bundesbank bank-code data, IBAN validation, KMyMoney-style personal finance applications, rbktoblzcheck, and konto_check.
