🎯 Why CryptEnv?

Modern development requires managing dozens of API keys, database credentials, and environment variables across multiple stacks. Sharing secrets over chat or storing them in plaintext `.env` files is a major security risk. Furthermore, when automating workflows with AI coding assistants (Claude Code, Cursor, MCP clients), sharing API keys in prompts exposes them to logs and external context windows.

**CryptEnv solves this by providing:**

Zero Plaintext Leaks: All secrets are encrypted at rest with AES-256-GCM and Argon2id. Master keys live only in volatile memory during active sessions.
AI Agent Integration via MCP: The built-in Model Context Protocol (MCP) server injects environment variables directly into subprocesses without returning plaintext secrets to the LLM.
Projects & Environments: Group variables by project (dev, staging, prod) and inject them directly into your local .env files with a single click or command.
Multiple Interfaces: Use the sleek desktop GUI, the full-featured crypt-env tui terminal interface, the CLI, or the local REST API.
