The output follows the familiar Part A / Part B Schedule form — Part A describing the electronic record and how it was produced, Part B listing the device and the hash values — so it reads the way a court expects. If you want to see the structure first, this Section 65B certificate format with an example is a useful reference.

Step 6 — Sign and Timestamp

Finally, make the certificate tamper-evident. e-Dex can apply a PAdES digital signature using a Digital Signature Certificate (DSC) on a USB token, binding the signer's identity to the document so any later edit is detectable. It can also attach an RFC-3161 trusted timestamp from a Time-Stamping Authority, providing independent proof that the certificate existed in that exact form at that moment. Both steps run from your own Windows machine; only the timestamp touches the internet, and everything else stays fully offline.

P26 (the successor to Section 65B of the Indian Evidence Act) they generally need to be accompanied by a certificate to be admitted. They are not automatically admissible just because they appear on a screen. e-Dex helps you produce a well-structured certificate that records the device, the export and the integrity hashes, but admissibility is ultimately decided by the court on the facts of the matter.

Is a WhatsApp screenshot enough for court?
Usually not on its own. A screenshot is secondary evidence that can be cropped, edited or fabricated, and it carries no proof of its source or that it has not been altered. Indian courts generally expect electronic records to be supported by a certificate. A better approach is to export the actual chat, hash the exported files and certify them so the bytes can be verified.

How do I get a Section 65B / Section 63 certificate for a WhatsApp chat?
Preserve the phone and the account, export the chat with WhatsApp's built-in Export chat feature (or have a forensic examiner extract it), record the device and account particulars, hash the exported files with a tool such as e-Dex, and then generate a Section 63 BSA / Section 65B electronic-evidence certificate that records the device, the export method and the integrity hashes with a MATCH verification. You can then sign it with a Digital Signature Certificate and apply a trusted timestamp.

Can WhatsApp messages be faked or edited?
Screenshots can be trivially edited, and messages can be deleted or disappear automatically, which is exactly why a bare screenshot is weak. Hashing the exported chat files does not prove the conversation is genuine on its own, but it does fingerprint the exact bytes so anyone can confirm the file has not changed since it was certified. Preserving the original device strengthens the picture further.

Do I need the original phone to certify a WhatsApp chat?
You need access to the phone or account to export the chat in the first place, and preserving the original device is strongly recommended because it supports chain of custody and lets an examiner re-verify the source if questioned. e-Dex itself does not connect to the phone; it hashes and certifies the files you have already exported, so once you have the export you can certify it on your own Windows machine.

Conclusion

A WhatsApp chat can win or sink a case — but only if you present it as more than a screenshot. Preserve the device, export the chat, record the particulars, hash the files and wrap them in a signed, timestamped Section 63 certificate, and you give the court something it can actually verify. Let WhatsApp or a forensic examiner produce the export, then let e-Dex — the Digital Evidence Integrity Suite hash the exhibits, capture the details and generate a court-ready certificate on your own Windows machine, fully offline and free to try.
