Overview Encypher Core provides tools for invisibly encoding metadata (such as model information, timestamps, and custom data) into text generated by AI models. This enables: - Provenance tracking : Identify which AI model generated a piece of text - Timestamp verification : Know when text was generated - C2PA-Compatible Manifests : Embed manifests inspired by the C2PA standard, with support for CBOR encoding for maximum interoperability. - Custom metadata : Embed any additional information you need - Tamper detection using digital signatures : Verify text integrity using digital signatures - Streaming support : Works with both streaming and non-streaming LLM outputs - LLM integrations : Ready-to-use integrations with OpenAI, Google Gemini, Anthropic Claude, and more - Modular architecture : Clean separation of key management, payload handling, and signing operations The encoding is done using Unicode variation selectors, which are designed to specify alternative forms of characters without affecting text appearance or readability. Relationship with C2PA Encypher implements the Coalition for Content Provenance and Authenticity (C2PA) standard for plain-text environments using the C2PA Text Embedding Standard . The core library uses the c2pa-text reference implementation for text manifest wrappers.
