Content Provenance and Authenticity

ImageMagick integrates the C2PA coder to embed and verify content provenance using cryptographic keys, certificates, and manifests. This enables trusted workflows for digital assets.

Encoding Example

Use the following command to encode provenance information into an image:

magick input.png \
  -define c2pa:key=mykey.pem \
  -define c2pa:cert=mycert.pem \
  -define c2pa:manifest=manifest.json \
  c2pa:output.png

Decoding Example

To inspect and verify the embedded C2PA data, run:

magick identify c2pa:output.png

Conclusion

The C2PA coder extends ImageMagick’s capabilities by allowing developers to encode and decode provenance metadata alongside standard image processing tasks.
