What is Digital Signature Software?

Digital signature software, also known as electronic signature or e-signature software. enables individuals and organizations to securely sign electronic documents using cryptographic technology that verifies authenticity, integrity, and signer identity. It replaces traditional handwritten signatures with legally recognized digital equivalents that comply with standards such as eIDAS, ESIGN, and UETA. These platforms use public key infrastructure (PKI) to encrypt and validate signatures, ensuring that documents cannot be altered after signing. Many solutions integrate with workflows, email, and document management systems to streamline contract approvals and reduce paperwork. By providing security, efficiency, and legal compliance, digital signature software has become essential for modern business transactions across industries.
