It works using cryptographic technology known as Public Key Infrastructure (PKI).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A digital signature ensures:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The signer is genuine<\/li>\n\n\n\n<li>The document has not been modified after signing<\/li>\n\n\n\n<li>The signer cannot deny signing the document<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Unlike a simple scanned signature image, a digital signature provides strong security and legal validity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>How Does a Digital Signature Work?<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"624\" height=\"348\"

sizes=\"(max-width: 624px) 100vw, 624px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Digital signatures use two cryptographic keys:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Private Key<\/strong> \u2013 Used by the signer to sign the document<\/li>\n\n\n\n<li><strong>Public Key<\/strong> \u2013 Used by others to verify the signature<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The Process<\/strong><\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li>A user signs a document digitally using their private key<\/li>\n\n\n\n<li>The system generates a unique encrypted hash of the document<\/li>\n\n\n\n<li>If the document is changed after signing, the signature becomes invalid<\/li>\n\n\n\n<li>Recipients verify the signature using the public key<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">This ensures trust, security, and tamper protection.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"1430\" height=\"780\"
