# C2PA Content Credentials

> Use this tool when you need to verify the authenticity of digital content and ensure its trustworthiness. It solves problems related to content validation and authenticity by checking against official trust lists, providing a secure way to read and verify credentials from local files or URLs. It is particularly useful when working with sensitive or high-stakes content that requires verification, such as news articles or official documents, and supports both past and future content signing standards.
