Establishing an evidentiary Priority Date should be accessible, instantaneous, and final. HashPaper operates strictly on a per-certificate basis with no subscriptions and no hidden retention fees. You pay once, the math is calculated, the certificate is generated, and the transaction is complete.
SHA-256 Cryptographic Processing
Military-grade one-way mathematical hashing of your raw text payload directly in volatile memory.
Section 63 Compliant PDF Certificate
A dynamically generated 3-page evidentiary document establishing your legal Priority Date.
Permanent Public Ledger Entry
Your masked metadata and hash are permanently etched into our searchable database for third-party verification.
Zero-Retention Privacy Guarantee
Instantaneous purging of your raw intellectual property from our servers the millisecond the hash is generated.
Everything you need to know before minting.
No. The ₹499 fee is a one-time payment for the computational processing and permanent ledger entry. Your Priority Date is established forever without recurring charges or "storage" fees.
No. Because of the strict nature of the SHA-256 algorithm, altering even a single comma completely changes the mathematical hash. If you update your script or code, you must mint a new certificate to establish a new Priority Date for that version.
We currently maintain a strict flat-fee structure to ensure operational transparency across all users. However, high-volume legal practices requiring API integration can contact our Verification Team for specialized infrastructure discussions.
No. Because we operate on a Zero-Retention architecture, we do not keep a backup of your text. It is entirely your responsibility to safely store the exact text you hashed alongside your PDF certificate. All minting sales are mathematically final.
