Verae timestamping

Full browser client matching the Mac app: hash files locally (WASM, WebCrypto fallback), Register or Verify digests via MCP, green/red status lights, auth defaults, and CSV / JSON / PDF / text export. File bytes never leave this device.

Verae Timestamping (Browser)

This page hashes files in your browser (SHA-256 WASM or Web Crypto), then
calls the Verae MCP with digests only — file bytes never upload.

• Register = look each digest up for free; documents already registered
  show their original time. New documents need Sign in with Verae (the
  same sign-in as the Verae apps); the price and your balance are shown
  before anything is charged. Receipts are saved in a local map
  (localStorage, keyed by sha256), similar to ~/.verae/receipts on Mac.
• Verify = look up local receipt → MCP verify by receipt_id; or use a
  pasted receipt_id. Does NOT stamp. If no receipt is known → Not found.
• Green check = found / valid / registered · Red octagon = not found /
  invalid / error. SHA-256 is always shown when hashed.
• Sign-in keeps a per-tab Verae key in sessionStorage only (gone when the
  tab closes; Sign out revokes it). No password or key is stored in
  localStorage or cookies. Lookups and Verify never send the key.
