Release notes

Version 0.6.0

See Release tag 0.6.0.

Breaking changes

The signature of the c2pa.sign_ps256() method changed. Previously, the argument was a file path but now its the PEM certificate string.

Version 0.5.2

New features:

  • Allow EC signatures in DER format from signers and verify signature format during validation.
  • Fix bug in signing audio and video files in ISO Base Media File Format (BMFF).
  • Add the ability to verify PDF files (but not to sign them).
  • Increase speed of sign_file by 2x or more, when using file paths (uses native Rust file I/O).
  • Fixes for RIFF and GIF formats.

Version 0.5.0

New features in this release:

  • Rewrites the API to be stream-based using a Builder / Reader model.
  • The functions now support throwing c2pa.Error values, caught with try/except.
  • Instead of c2pa.read_file you now call c2pa_api.Reader.from_file and reader.json.
  • Read thumbnails and other resources use reader.resource_to_stream or reader.resource.to_file.
  • Instead of c2pa.sign_file use c2pa_api.Builder.from_json and builder.sign or builder.sign_file.
  • Add thumbnails or other resources with builder.add_resource or builder.add_resource_file.
  • Add Ingredients with builder.add_ingredient or builder.add_ingredient_file.
  • You can archive a Builder using builder.to_archive and reconstruct it with builder.from_archive.
  • Signers can be constructed with c2pa_api.create_signer.
  • The signer now requires a signing function to keep private keys private.
  • Example signing functions are provided in c2pa_api.py

Version 0.4.0

This release:

  • Changes the name of the import from c2pa-python to c2pa.
  • Supports pre-built platform wheels for macOS, Windows and manylinux.

Version 0.3.0

This release includes some breaking changes to align with future APIs:

  • C2paSignerInfo moves the alg to the first parameter from the 3rd.
