The BSA Schedule requires Part B to be signed by an Expert (Name, Designation & Signature). Select a signing mode, then fill in the details. These fields are optional — if left blank, Part B generates with blank signature lines as before.
MODE A — LEGAL BASIS FOR SELF-CERTIFICATION: Under Interpretation (i) of Section 63(4) BSA, the person who personally operated the hash terminal and has direct knowledge of the computation process may sign Part B. The BSA Schedule specifies no minimum qualification for the Part B signatory. This interpretation is supported by leading Indian legal commentators (LiveLaw, 2024; Obiter.in, 2025) and is the most commonly adopted approach at the district court level. If challenged at the High Court level, be prepared to defend it — the question of who qualifies as "Expert" under Section 63 remains unsettled by the Supreme Court. This guidance is not printed in the generated certificate PDF.

Independent Hash Verification
For opposing counsel, courts, or any party seeking to independently verify the integrity of a file against a
stated SHA-256 hash value. Drop the file and enter the expected hash — this tool will confirm whether they match.
