HMAC
Hash-based Message Authentication Code — cryptographic signature for verifying message integrity.
HMAC produces a signature you can verify but can't forge without the secret. CLAWVR uses HMAC-SHA256 to sign every resource URL (snapshot links, tracking pixels, click redirects) — knowing a lead ID is no longer enough to access their data.
