About:
c2patool is a command-line interface (CLI) utility for creating, reading, and verifying C2PA (Coalition for Content Provenance and Authenticity) manifests. It embeds cryptographic provenance and tamper-evident metadata into media assets like images and videos. This tool is essential for developers implementing content authenticity features to combat misinformation and verify digital media origins.
|
Key Features:
- Create and sign C2PA manifests with cryptographic credentials
- Read and parse existing C2PA manifest data from media files
- Verify the integrity and authenticity of signed content
- Support for various media formats including JPEG, PNG, and MP4
- Integration with hardware signing keys for enhanced security
|
Use Cases:
- Embedding provenance metadata into AI-generated images to indicate synthetic origins
- Verifying the authenticity of photojournalism content before publication
- Developing applications that require tamper-evident media logging
- Auditing content supply chains for digital rights management
|
Alternatives:
-
exiftool
– General-purpose metadata editor that lacks C2PA-specific signing and verification capabilities
-
c2pa-rs (library)
– The underlying Rust library; c2patool provides a convenient CLI wrapper for it
