C2PA C API
This is the C API wrapper for the C2PA Rust SDK. It provides a C-compatible interface for working with content credentials, with same formats supported as the Rust SDK. This crate can also be used in Rust code to write C-compatible bindings with the exposed types.
Overview
The C2PA C API allows developers to integrate content authenticity features into their applications using C or any language that can interface with C libraries.
Building locally
Pre-requisite: You will need the Rust toolchain (cargo) installed.
To build and test locally, run:
make test
The build will have 2 features activated: rust_native_crypto and file_io.
Note that running the make test command will also check formatting of the code.
