Backend: Implement API key generation and hashing service

[supreme2580]

Description
Allow merchants to generate secure API keys for server-to-server integrations.

Requirements

• Create POST /apikeys endpoint.
• Logic:
  • Generate 32-byte cryptographically random key.
  • Prefix with sp_live_.
  • Store only the SHA256 hash of the key in the database (key_hash).
• Response: Return the plaintext key only once to the merchant.

I’d love to tackle this backend task. I have experience setting up API key generation workflows and can get the POST /apikeys route, hashing service, and single-exposure plaintext response implemented cleanly and securely..
