3-Layer IP Masking & Cloudflare Edge Relay Architecture

Direct outbound webhooks from backend servers expose origin IP addresses in destination server logs, leaving cloud infrastructure vulnerable to tracing and targeted attacks. AliasMail uses a 3-Layer Edge Relay architecture powered by Cloudflare Workers to proxy outbound webhook requests.

HMAC-SHA256 Payload Signature Verification

Destination servers only log Cloudflare edge IP addresses (104.28.x.x / 2400:cb00::), completely concealing backend NestJS server IPs, hosting providers, and internal topology.

SSRF Protection & Subnet Security Guards

Every webhook dispatch includes an HMAC-SHA256 signature header (X-AliasMail-Signature) computed using Web Crypto API. Recipients can verify signature authenticity using their custom secret key while receiving sub-50ms real-time email payloads.

알아야 할 모든 것

임시 이메일, 전달 별칭 및 로그 미저장 아키텍처에 대해 알아야 할 모든 것.

01How does masked webhook delivery hide my origin IP?
Outbound webhook requests are routed through a Cloudflare Worker relay. The destination server sees Cloudflare edge IPs, keeping your backend server IP completely hidden.
02How do I verify the HMAC-SHA256 signature in my code?
Calculate HMAC-SHA256 of the raw request body using your secret key and compare it with the X-AliasMail-Signature header.
03Are internal subnets protected against SSRF?
Yes. The relay inspects destination URLs and blocks requests targeting localhost (127.0.0.1) and private RFC 1918 subnets (10.0.0.0/8, 192.168.0.0/16).
