A digital signature in Zoho Sign uses Public Key Infrastructure (PKI) to create a cryptographic proof that a specific person signed a document and that the document has not been altered since signing. Each digital signature is mathematically linked to both the signer’s identity certificate and the document content.<\/p>\n
The signer uses a digital signing certificate (issued by a trusted Certificate Authority) to sign the document. Zoho Sign embeds the signature as cryptographic data within the PDF. Anyone can verify the signature by checking it against the signer’s public key and confirming the document hash matches the original.<\/p>\n
Digital signatures are required in heavily regulated industries and government procurement in India (using DSC), for legally binding commercial contracts where non-repudiation is critical, and under the eIDAS Qualified Electronic Signature standard for high-assurance EU transactions. For standard commercial agreements, a standard electronic signature usually suffices.<\/p>\n
A Digital Signature uses a certificate-based cryptographic key to bind the signer’s identity to the document. Any alteration to the document after signing invalidates the signature mathematically, providing tamper evidence. A standard electronic signature (such as a drawn or typed signature) does not have this cryptographic binding and relies on audit trail evidence for integrity rather than mathematical verification.<\/p>\n<\/div>\n
Digital Signatures are required for documents where regulations mandate certificate-based authentication, such as certain government filings, court submissions, or regulated financial agreements. They are also appropriate where counter-party trust is lower and stronger identity assurance is needed. For routine commercial contracts where parties are known and trust is established, standard electronic signatures with a strong audit trail are sufficient.<\/p>\n<\/div>\n
