Anyone sent you a backtest? Check it here. If the report was produced and signed by the
Honest Backtest Engine, this page proves it hasn't been altered since — the check runs entirely in your
browser, and the file never leaves your machine.
Accepts a signed report (.html) or a raw signature envelope (.json).
Nothing is uploaded — verification is local.

The numbers above come from the signed data itself, not from the document's visible text —
if the document you were sent shows different figures, the visible text was edited after signing.
One thing cryptography can't do: it proves this report is untouched since the key
signed it — not who owns that key. If it matters, ask the sender
to confirm their key fingerprint through another channel (it's shown in their engine and on every
report they sign). Same fingerprint = same signer.
How this works
Every signed report carries a cryptographic signature (Ed25519) over the full recomputed results —
every trade, every metric — made at signing time on the signer's own machine. Change a single character
of the signed data and the signature breaks. This page checks that signature and shows you what was
actually signed. No accounts, no server, no trust in us required — the same check can be run offline
with the verify_report.py tool that ships with the engine.
