Digital signatures are a form of electronic signature that uses cryptographic techniques to provide secure and verifiable means of signing electronic documents. They are widely recognized and accepted as legally binding in many jurisdictions around the world. The enforceability of digital signatures is backed by various laws and regulations that recognize electronic signatures as equivalent to handwritten signatures, provided they meet certain criteria for authenticity and integrity. For instance, in the United States, the ESIGN Act establishes the legal validity of electronic signatures, including digital signatures1. Similarly, the eIDAS regulation in the European Union provides a legal framework for electronic signatures and trust services, including digital signatures2.
