Enum SignatureAlgorithm 

#[non_exhaustive]
pub enum SignatureAlgorithm {
    HmacSha256,
    StripeWebhooks,
    HmacSha256Base64,
    Ed25519,
}

Supported signature algorithms.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

HmacSha256

HMAC-SHA256 (e.g., GitHub)

StripeWebhooks

Stripe webhook format.

Signs {timestamp}.{body} with HMAC-SHA256. Timestamp and signatures are extracted from the Stripe-Signature header (t=...,v1=...). Requests older than 5 minutes are rejected to prevent replay attacks.

HmacSha256Base64

HMAC-SHA256 with base64-encoded output (e.g., Shopify).

Same algorithm as HmacSha256 but the signature is base64-encoded instead of hex.

Ed25519

Ed25519 asymmetric signature verification.

The secret_env holds a base64-encoded Ed25519 public key (32 bytes). Used by services that sign with a private key and distribute a public key for verification.

Implementations

impl SignatureAlgorithm

pub fn prefix(&self) -> &'static str

Get the algorithm prefix used in signatures (e.g., “sha256=”).

Returns an empty string for algorithms that don’t use a simple prefix.

Trait Implementations

impl Clone for SignatureAlgorithm

fn clone(&self) -> SignatureAlgorithm

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SignatureAlgorithm

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for SignatureAlgorithm

fn eq(&self, other: &SignatureAlgorithm) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
