Struct SignedObject

pub struct SignedObject(pub(crate) CoseSign1);

A signed object is a message containing a payload and signature that attests the payload’s integrity and authenticity for a specific namespace and signature key. In order to gain access to the payload, the caller must provide the correct namespace and verifying key, ensuring that the caller cannot forget to validate the signature before using the payload.

Implementations

impl SignedObject

pub fn content_type(&self) -> Result<CoapContentFormat, CryptoError>

Parses the signature headers and returns the content type of the signed data. The content type indicates how the serialized message that was signed was encoded.

fn inner(&self) -> &CoseSign1

fn namespace(&self) -> Result<SigningNamespace, CryptoError>

fn payload(&self) -> Result<Vec<u8>, CryptoError>

pub fn verify_and_unwrap<Message: DeserializeOwned>( &self, verifying_key: &VerifyingKey, namespace: &SigningNamespace, ) -> Result<Message, CryptoError>

Verifies the signature of the signed object and returns the payload, if the signature is valid.

fn verify_and_unwrap_bytes( &self, verifying_key: &VerifyingKey, namespace: &SigningNamespace, ) -> Result<Vec<u8>, CryptoError>

Verifies the signature of the signed object and returns the payload as raw bytes, if the signature is valid.
