Enum EnvelopeFormat 

pub enum EnvelopeFormat {
    Raw,
    StripeV1,
    SlackV0,
    GithubHmac,
}

Selector for how a webhook signature header should be parsed, and the resulting HMAC signing-input shape.

Each variant maps to a real-world signing scheme used by a major developer-facing API. Adding a new variant means: extending this enum, extending parse_envelope in src/rules.rs, extending the signing_input match in WebhookSignatureMismatch::evaluate, and extending the envelope_format enum in cases.schema.json.

Variants

Raw

Header value is a raw hex digest, optionally prefixed sha256=. Timestamp comes from a separate timestamp_header. Signing input: "{ts}.{body}".

StripeV1

Stripe-style envelope: t=<unix_ts>,v1=<sig>,v0=<sig>,.... Timestamp comes from the envelope’s t= field; timestamp_header is ignored. Signing input: "{ts}.{body}".

SlackV0

Slack v0 envelope: X-Slack-Signature: v0=<hex>. Timestamp comes from a separate X-Slack-Request-Timestamp header. Signing input: "v0:{ts}:{body}".

GithubHmac

GitHub-style HMAC: X-Hub-Signature-256: sha256=<hex>. There is no timestamp claim; webhook_timestamp_stale cannot fire. Signing input: {body} (raw body, no prefix).
