What is SHA256 evidence hashing?

SHA-256 evidence hashing creates a unique fingerprint (hash) of a digital file. If the file changes even slightly, the SHA-256 hash changes, helping prove integrity of digital evidence.

Is this valid in court?

SHA-256 hashing is widely used to demonstrate integrity of electronic records. For filings, always follow your court’s practice directions and verify compliance requirements under the Bharatiya Sakshya Adhiniyam and related evidence act procedures.

How to verify digital evidence?

Generate the SHA-256 hash at collection time and record it in your documentation/affidavit. Later, re-hash the same file and compare values to verify the digital evidence has not been altered.

Frequently Asked Questions

You input a SHA-256 hash (usually from a printed affidavit) and upload the original digital file. The system re-calculates the file's hash and compares it. A match proves the file is identical to the one originally hashed.

The Bhartiya Sakshya Adhiniyam (BSA) specifies SHA-256 as a secure standard for ensuring the integrity of digital evidence. It prevents tampering and provides a unique "fingerprint" for every file.

Yes. The report records both hash values in full, the file details, when and how the check was made, and a blockchain timestamp of the file's hash. Verifying is free; the print-ready report PDF costs 3 credits and is emailed to you.

Yes. We utilize the Web Crypto API, which runs the hashing algorithm entirely on your local CPU. Your files never touch our servers.

Electronic evidence — common questions

Section 63(4) of the Bharatiya Sakshya Adhiniyam, 2023. Since 1 July 2024 the certificate follows the form in the BSA Schedule, in two parts (Part A by the person in charge of the device, Part B by an expert), and names the record by its hash value.

A hash is the file’s fingerprint: change one character and the SHA-256 value changes completely. Matching hashes show the court is looking at the same record you certified. The Supreme Court called the hash value an electronic fingerprint in Pune Bar Association v. Union of India (22 May 2026).

No. EvidenceHash calculates the SHA-256 hash in your browser; the file stays on your device.

Yes. Export the chat, hash the exported file, and certify that file under Section 63(4).

Why EvidenceHash

Section 63 BSA ready
SHA-256 is the standard Indian courts expect for electronic evidence under the Bharatiya Sakshya Adhiniyam (old Section 65B).
Reverse check for courts
Anyone can re-verify a file later against the hash recorded in an affidavit — a match proves it is unchanged.
Your file never leaves your device
The hash is computed in your browser. Only when you buy a PDF is the 64-character hash itself (never the file) timestamped and kept in your history.
Court-ready PDFs
A Section 63 affidavit and a verification report, each with a blockchain timestamp of the file’s hash, emailed to you with the proof.

BSA-compliant digital evidence authentication

EvidenceHash is a digital evidence authentication tool built for Indian advocates under the Bharatiya Sakshya Adhiniyam (BSA). As courts increasingly accept electronic records, a SHA-256 hash is the simplest reliable way to show that a document, photograph, video or chat export has not been altered since it was collected.

Generate the hash, put it in your Section 63 certificate or affidavit, and verify the same file against it whenever it is questioned. Every report includes the SHA-256 value, the file details and when the check was made, so it is ready to file.
