Title: Prepare Verifiable Uber & Waymo Evidence Package Using Python Description: We need a freelancer to help prepare verifiable evidence for Uber and Waymo trip data for patent/legal purposes. The freelancer will not access any accounts or private keys. All raw data will be provided by us. The freelancer’s task is to automate the creation of: Metadata JSON SHA256 hash Detached digital signatures (using OpenSSL command provided) Properly formatted evidence package ready for submission --- Requirements Python 3 experience (Pydroid 3 or desktop Python) Experience with JSON handling and SHA256 hashing Familiarity with OpenSSL and generating detached signatures Attention to detail — evidence must be court-ready Ability to write a script that processes raw data files and outputs metadata, hashes, and signature commands --- Deliverables For both Uber and Waymo (data provided by us): 1. Metadata JSON files: Include client ID, endpoint (if applicable), timestamp (UTC), token type, SHA256 hash. 2. SHA256 hash of provided trip data JSON. 3. OpenSSL command to generate detached signature. 4. Python script used to automate this process. --- Instructions for Freelancer 1. Accept raw trip data files (trip_data.json) from us. 2. Write a Python script to: Compute SHA256 hash of the JSON file Generate metadata JSON using a given template Output OpenSSL command for detached signature 3. Deliver: trip_data.meta.json SHA256 hash (inside metadata) OpenSSL signature command Python script used --- Metadata JSON Template { "client_id": "<CLIENT_ID>", "access_token_type": "<TOKEN_TYPE>", "endpoint": "<API_ENDPOINT>", "fetch_time_utc": "<YYYY-MM-DDTHH:MM:SSZ>", "sha256": "<SHA256_HASH_OF_JSON>", "script": "<SCRIPT_NAME>" } --- Important Notes Freelancer will not receive credentials. All processing must be done on provided files. Evidence package must be verifiable and ready for submission. --- If you want, I can also draft a Python template that the freelancer can fill in — it will automatically: Take raw JSON files (Uber or Waymo) Compute SHA256 hash Generate metadata JSON Print OpenSSL detached signature command This makes it ready for immediate use and speeds up the job.
