Struct HmacVerificationKey 

pub struct HmacVerificationKey { /* private fields */ }

Caller-owned HMAC verification key.

Policy-free VerifyingKey calls enforce crate::policy::HmacPolicy::default. super::VerifyContext supplies its immutable operation policy through the policy-aware hooks, so legacy truncation always requires an explicit opt-in. Owned secret bytes are zeroized when the key is dropped.

Implementations

impl HmacVerificationKey

pub fn new(secret: impl Into<Vec<u8>>) -> Result<Self, KeyResolutionError>

Construct a key from non-empty secret bytes.

Trait Implementations

impl Clone for HmacVerificationKey

fn clone(&self) -> HmacVerificationKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HmacVerificationKey

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

Formats the value using the given formatter.

impl VerifyingKey for HmacVerificationKey

fn validate_policy(&self, policy: &VerificationPolicy) -> Result<(), DsigError>

Validate this key against the operation’s immutable trust policy.

fn validate_signature_value( &self, algorithm: SignatureAlgorithm, signature_value: &[u8], ) -> Result<bool, DsigError>

Check that signature_value has the wire framing required by the declared algorithm and this key before provider dispatch.

fn validate_signature_value_with_policy( &self, policy: &VerificationPolicy, algorithm: SignatureAlgorithm, signature_value: &[u8], ) -> Result<bool, DsigError>

Validate wire framing under the operation’s immutable compatibility policy.

fn verify( &self, algorithm: SignatureAlgorithm, signed_data: &[u8], signature_value: &[u8], ) -> Result<bool, DsigError>

Verify signature_value over signed_data with the declared algorithm.

fn verify_with_policy( &self, policy: &VerificationPolicy, algorithm: SignatureAlgorithm, signed_data: &[u8], signature_value: &[u8], ) -> Result<bool, DsigError>

Verify after applying operation-scoped compatibility semantics.
