Bioseal SDK is a toolkit that secures documents—both digital and printed—by embedding cryptographic digital signatures into visible digital seals (typically QR codes) to ensure authenticity and integrity. It leverages international standards and a robust trust framework for universal, easy verification of document legitimacy while offering cross-platform compatibility across various programming languages and environments.

This user guide is intended to help developers quickly get started with the SDK, covering the setup, basic operations, advanced features, and troubleshooting tips to ensure a smooth integration process.
