If you find a security issue in the DataMatrix generator library (dmgen) — the library, the C ABI, the Python package, the dmgen command-line tool or the license check — please report it privately by email to libscanner@yandex.com rather than opening a public issue.

Please include the product version (dmgen --help prints it on the first line), the platform, and the steps or input needed to reproduce the problem. We will acknowledge the report and keep you informed about the fix.

Supported version: 1.0.x.
