Code Prism

Zero Code Exposure for AI Coding Assistants

Code Prism is a VS Code extension that provides end-to-end encryption for AI coding assistants using Fully Homomorphic Encryption (FHE). Your code never leaves your machine unencrypted - the AI processes encrypted data without ever seeing your plaintext.

What is Code Prism?

Code Prism is a security-first VS Code extension that enables you to use AI coding assistants like GitHub Copilot with complete code privacy. Using advanced Fully Homomorphic Encryption (FHE), Code Prism ensures that:

• ✅ Your code is always encrypted before it leaves your device
• ✅ AI servers process encrypted data without ever seeing plaintext
• ✅ Only your device can decrypt the AI's responses
• ✅ No code exposure risk from compromised servers or networks

Key Features

🔒 Always-On Encryption

• Automatic end-to-end encryption using FHE
• No toggle - encryption is always active
• Zero configuration required after initial setup

🛡️ Visual Protection Indicators

• Status Bar: Real-time encryption status (🛡️ Code Prism: Protected)
• Chat Badge: Every AI response shows 🔒 Protected by Code Prism
• Active Monitoring: See when encryption is actively processing requests

🔑 Client-Side Key Management

• Encryption keys never leave your device
• Stored securely in VS Code's secret storage
• Export/import for backup and device sync

🚀 Seamless Integration

• Works with GitHub Copilot Chat in VS Code
• Access powerful Mirror 70B and 7B models
• Full support for streaming responses
• Tool calling support for agentic workflows

📊 Debug & Verification

• Advanced settings to verify encryption is working
• View encrypted payloads and decrypt manually
• Detailed logging for security audits

What's Protected

When using Code Prism, the following data is encrypted end-to-end:

✅ All chat messages with AI assistants ✅ Code snippets shared with AI ✅ File contents when using @workspace or @files ✅ AI responses from the server ✅ Function/tool calls and their parameters

What's Stored Locally

• Client encryption keypair (VS Code secure storage)
• Server public keys (VS Code secure storage)
• API key (VS Code secure storage)

What's NEVER Sent Unencrypted

• Your source code
• Chat messages
• File contents
• Project context
