This example demonstrates how to create a cryptographic signature for a message using the Ethereum private key signing process. It shows the entire workflow of converting a plain-text message into a signed hexadecimal string via the `personalSign` function, which relies on the `ethereumjs-util` library. The code imports `ethUtil` to handle message hashing, elliptic curve signing, and serialization, using methods like `hashPersonalMessage`, `ecsign`, and `bufferToHex`. A hardcoded private key (`privKeyHex`) is passed to `personalSign` with the message `"terms"`, and the resulting signature is printed to the console.

This example shows a cryptographic proof of identity, linking a GitHub account to a Keybase profile through a signed JSON message and a PGP signature. It displays the plaintext of the proof, including the public key fingerprint, the JSON body, and the armored PGP message, as a formatted document. The gist file contains no executable visualization code, so no JavaScript or rendering libraries are used. Instead, the content is presented as raw text within a single file, relying on the gist interface for display.

This example demonstrates a cryptographic identity verification proof posted as a GitHub gist, using Keybase’s public-key infrastructure. It shows how a user (Ekthelion) claims ownership of both a GitHub account and a Keybase identity by embedding a signed JSON object that includes a fingerprint and a PGP signature. The code references the Keybase command-line tool and the OpenPGP API to generate and validate the signature. The visualization would render the JSON structure and signature block as textual data, highlighting the nested cryptographic fields and the verification steps without relying on graphical libraries.

This example demonstrates a cryptographic identity verification workflow, showing how a GitHub user proves ownership of their account through a signed Keybase statement. The visual focus is on the structured JSON payload, which contains the user’s public key, service binding details, and a Merkle root hash. The code uses the `crypto` module for signature validation and `JSON.stringify` to format the payload for display. It also references Keybase’s command-line interface and the public API for fetching identity data, with the rendered output emphasizing the signature’s provenance and auditability.

This example demonstrates a Keybase proof, a cryptographic identity verification that links a GitHub account to a Keybase username. The gist displays a signed JSON object and its corresponding signature, along with the public key and a command-line verification step. The code uses the Keybase API and command-line client to validate the identity, showing how the proof is structured and auditable. The rendering approach is plain-text, presenting the signed payload and metadata without any visualization libraries.

This example demonstrates a cryptographic identity verification workflow, showing how a GitHub user proves ownership of their Keybase account. It displays a JSON signature object alongside a plain-text explanation, with the rendered content illustrating the signed statement and its public key reference. The visualization uses standard web rendering through a simple HTML layout, relying on the GitHub gist interface to present the Keybase proof data. No external data visualization libraries are employed; instead, the code relies on basic DOM elements and CSS styling to display the structured proof content.

This example demonstrates a cryptographic identity verification workflow, showing how a user proves ownership of a GitHub account through the Keybase service. The gist contains a signed JSON object with a PGP message, linking the GitHub username "JoeYerardi" to the Keybase username "joeyerardi" via a public key fingerprint. The code relies on Keybase’s command-line interface and OpenPGP signing, using the `keybase id` command to look up and authenticate the user. The visible data includes the signed statement, the public key details, and the generated signature, all presented as a textual proof rather than a chart or graph. The rendering approach is plain-text code blocks, with no graphical libraries involved.

This visualization renders a Keybase proof as a cryptographic signature chain, showing the JSON object’s fields and the resulting signature hex string. It uses a custom layout to display the data as interconnected nodes and edges, likely built with d3’s force simulation or a similar graph library. The proof text, including the key ID and signature, is visible as text elements. The rendering emphasizes the structure of the signed payload and its verification steps.

This example demonstrates a Keybase identity proof by visually presenting the cryptographic signature that links a GitHub account to a Keybase user. The gist shows a JSON object containing the signed statement, along with the PGP-signed message and the public key fingerprint, all rendered as structured text. The visualization uses a plain-text layout to display the keybase.md file, highlighting the nested JSON and the encoded signature block without any additional charting or graphics libraries. The data source is the gist itself, and the rendering relies solely on HTML text formatting, with no interactive or dynamic elements beyond the static content.
