hashproof

Command line interface for the Hashproof Content Provenance API. Verify, store, resolve, and fingerprint digital assets from the terminal.

Install

Run it without installing, using npx:

npx hashproof status

Or install it globally:

npm install -g hashproof

Authentication

The verify, store, resolve, and fingerprint commands require an API key. Keys start with hpsk_. Save one with:

hashproof config set-key hpsk_your_key

You can also provide the key through the environment, which takes precedence over the saved key:

export HASHPROOF_API_KEY=hpsk_your_key

The status command does not require a key.

Commands

hashproof verify <file>          # Check a file's content provenance
hashproof store <file>           # Store a C2PA manifest for a file
hashproof resolve <file>         # Resolve provenance by soft binding
hashproof fingerprint <file>     # Compute a perceptual fingerprint
hashproof status                 # Report API service status
hashproof config set-key <key>   # Save your API key
hashproof config set-url <url>   # Set a custom API base URL
hashproof config show            # Show the current configuration

store accepts --title (-t) to set an asset title. fingerprint accepts --algorithm (-a), which defaults to phash-dct-64.

Configuration

Configuration is stored at ~/.hashproof/config.json. Two environment variables override the saved values:

• HASHPROOF_API_KEY overrides the saved API key.
• HASHPROOF_BASE_URL overrides the API base URL. The default is https://api.hashproof.ai.
