Non-blocking security: Asynchronous secret management with asyncio.

Synchronous database and crypto calls are the hidden concurrency killers in FastAPI microservices. wauth provides native async_set, async_get, and async_valid to keep your event loop running at full speed.

Here is the exact production implementation for Asynchronous API (async_set, async_get, async_valid):

import asyncio
from wauth import WAuth

auth = WAuth()

async def authenticate_request(api_key: str) -> bool:
    # Non-blocking, constant-time verification in async coroutine
    is_valid = await auth.async_valid("SERVICE_API_KEY", api_key)
    return is_valid

async def main():
    await auth.async_set("SERVICE_API_KEY", "sk_live_994821")
    authorized = await authenticate_request("sk_live_994821")
    print(f"Request authorized: {authorized}")

asyncio.run(main())

Why this changes developer velocity:

• Native Async Methods: async_set(), async_get(), async_delete(), and async_valid().
• FastAPI Optimized: Drop directly into async route dependencies with zero event loop stalling.
• Thread-Pool Delegated: Cryptographic computations are safely offloaded without blocking I/O.

Zero Pain:

• Synchronous database queries and crypto calls blocking the event loop in async microservices
• Slow request handling in FastAPI endpoints that frequently verify user API keys
• Concurrency bottlenecks when hundreds of concurrent coroutines query secrets simultaneously
