Codesigning

Artemis can extract some parts of macOS Codesigning metadata. Currently it only supports parsing the Requirements blob from Codesigning metadata.

Collection

You have to use the artemis api in order to parse Codesigning data.

Sample API Script

import { parseRequirementBlob } from "https://raw.githubusercontent.com/puffycid/artemis-api/master/mod.ts";

function main() {
  // Need to obtain alias bytes from another file. Plist files may have Codesigning data.
  // Ex: The macOS Firewall artifact contains codesigning data
  const results = parseRequirementBlob(new Uint8Array());
  // The macOS command: csreq -v -r- -t < bytes.raw
  // can be used to compare results
  console.log(results);
}

Output Structure

A SingleRequirement object structure

export interface SingleRequirement {
  identifier: string;
  team_id: string;
  cdhash: string;
}
