CLI (truestamp)
The open-source truestamp command-line client, a single static binary for macOS, Linux, and Windows that submits items, downloads proof bundles, and verifies proofs fully offline without an account, signing in through the browser as a pre-registered OAuth 2.1 PKCE client.
Overview
The truestamp CLI is Truestamp’s open-source terminal client: a single static
binary for macOS, Linux, and Windows with no runtime dependencies. It covers
the whole proof lifecycle from a shell: truestamp create hashes a file
locally and submits the claim, truestamp download fetches the
proof bundle once the item is committed, and
truestamp verify checks any proof fully offline, with no account and no call
to Truestamp (see offline verification).
For commands that act on your account it never asks for credentials in the
terminal: the CLI is a pre-registered, first-party
OAuth 2.1 client that signs you in through your
browser with the PKCE flow and renews access silently with refresh tokens.
Install methods, commands, and the sign-in details are in
the Truestamp CLI concept.
