Webhook Signature Verifier

A live webhook HMAC signature verifier: paste a payload, signing secret and the provider's expected signature, pick an algorithm (SHA-256/SHA-1/SHA-512) and encoding (hex/base64), and get the computed HMAC plus a constant-time valid/mismatch verdict. Auto-detects Stripe and prefixed signature formats.
