Xăng Gate

A Claude API gateway on local payments, two services split by RS256 JWT

A Vietnamese developer without an international credit card cannot buy an API key. Xăng Gate sits in between: it takes a domestic transfer and issues a key that works immediately with Claude Code or a compatible SDK.

Tách dịch vụ, xác thực bằng khoá bất đối xứng

ManaGate  ──  JWT ký RS256  ──▶  IRIS Proxy
(cửa hàng, dashboard,              (proxy tới nhà cung cấp AI,
 thanh toán, admin)                 rate limit, quota)

  POST /admin/keys/generate
  Authorization: Bearer <jwt>
    alg = RS256  (RsaSecurityKey, RsaSha256)

# Vì sao bất đối xứng: IRIS chỉ cần PUBLIC key để xác minh.
# Hai dịch vụ không phải chia sẻ secret đối xứng.

⚠ trong code: thiếu RSA private key thì rơi về alg = None với khoá rỗng.
   Chỉ hợp lệ cho môi trường dev.
