Struct CoseMac 

pub struct CoseMac {
    pub protected: ProtectedHeader,
    pub unprotected: Header,
    pub payload: Option<Vec<u8>>,
    pub tag: Vec<u8>,
    pub recipients: Vec<CoseRecipient>,
}

Structure representing a message with authentication code (MAC).

 COSE_Mac = [
    Headers,
    payload : bstr / nil,
    tag : bstr,
    recipients :[+COSE_recipient]
 ]

Fields

protected: ProtectedHeader

unprotected: Header

payload: Option<Vec<u8>>

tag: Vec<u8>

recipients: Vec<CoseRecipient>

Implementations

impl CoseMac

pub fn verify_tag<F, E>(&self, external_aad: &[u8], verify: F) -> Result<(), E>

where F: FnOnce(&[u8], &[u8]) -> Result<(), E>,

👎Deprecated: Use verify_payload_tag() to ensure payload is present

Verify the tag value using the provided mac function, feeding it the tag value and the combined to-be-MACed data (in that order).

Panics

This function will panic if the payload has not been set.

pub fn verify_payload_tag<F, E, G>( &self, external_aad: &[u8], missing_payload_error: G, verify: F, ) -> Result<(), E>

where F: FnOnce(&[u8], &[u8]) -> Result<(), E>, G: FnOnce() -> E,

Verify the tag value using the provided mac function, feeding it the tag value and the combined to-be-MACed data (in that order). If the CoseMac has no payload, then missing_payload_error() will be returned.

Trait Implementations

impl AsCborValue for CoseMac

fn from_cbor_value(value: Value) -> Result<Self>

Convert a Value into an instance of the type.

fn to_cbor_value(self) -> Result<Value>

Convert the object into a Value, consuming it along the way.

impl CborSerializable for CoseMac

fn from_slice(slice: &[u8]) -> Result<Self>

Create an object instance from serialized CBOR data in a slice. This method will fail (with CoseError::ExtraneousData) if there is additional CBOR data after the object.

fn to_vec(self) -> Result<Vec<u8>>

Serialize this object to a vector, consuming it along the way.

impl Clone for CoseMac

fn clone(&self) -> CoseMac

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CoseMac

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

Formats the value using the given formatter.

impl Default for CoseMac

fn default() -> CoseMac

Returns the “default value” for a type.

impl PartialEq for CoseMac

fn eq(&self, other: &CoseMac) -> 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.

impl TaggedCborSerializable for CoseMac

const TAG: u64 = 97u64

The associated tag value.

fn from_tagged_slice(slice: &[u8]) -> Result<Self>

Create an object instance from serialized CBOR data in a slice, expecting an initial tag value.

fn to_tagged_vec(self) -> Result<Vec<u8>>

Serialize this object to a vector, including initial tag, consuming the object along the way.
