SHA-256 E-Sign Vault & Legal Contracts

Legally binding digital contracts with 5-step guided wizard, GST verification, canvas signatures, and Indian IT Act 2000 compliance.

The Document Vault is Cora's legal and compliance engine. It eliminates paper agreements and expensive third-party tools (DocuSign, PandaDoc) by providing unlimited, cryptographically verified digital contracts.


1. 5-Step Guided Signing Wizard

Clients sign agreements through a smooth, progressive 5-step flow:

  1. Details: Contract metadata, parties involved, shoot date, and deliverables scope.
  2. Terms: Full scroll-to-bottom agreement terms with explicit checkbox clauses.
  3. GST Math: Clear commercial calculation displaying Base Fee + 18% GST (CGST/SGST).
  4. E-Sign Pad: HTML5 signature canvas with typed-name fallback and timestamp recording.
  5. Complete: Instantly generates an encrypted, watermarked signed PDF copy for both parties.

2. Indian IT Act 2000 Compliance

All signatures captured in Cora comply with Sections 4 and 5 of the Indian Information Technology Act, 2000 for electronic contract execution:

  • Signer IP address and browser user-agent are immutably bound to the record.
  • Exact date and time (IST) are stamped on every page.
  • Cryptographic SHA-256 hash guarantees the document has not been altered post-signature.
