🛠 Sigil: Cryptographic Protection for LLM Prompts
Sigil has been released — an open-source tool for protecting LLM prompts. The system uses Ed25519 signatures to ensure instruction integrity, implements trust boundaries via XML tags, and normalizes input data to prevent tampering.
🌍 The tool offers an alternative to expensive Enterprise AI Governance platforms, shifting security control from cloud servers to local cryptographic verification.
👤 Developers can implement security standards (protection against prompt injection, auditing) without relying on proprietary SaaS solutions.
