Struct coset::CoseRecipient

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

Structure representing the recipient of encrypted data.

 COSE_Recipient = [
     Headers,
     ciphertext : bstr / nil,
     ? recipients : [+COSE_recipient]
 ]

Fields

protected: ProtectedHeader

unprotected: Header

ciphertext: Option<Vec<u8>>

recipients: Vec<CoseRecipient>

Implementations

impl CoseRecipient

pub fn decrypt<F, E>( &self, context: EncryptionContext, external_aad: &[u8], cipher: F ) -> Result<Vec<u8>, E>where F: FnOnce(&[u8], &[u8]) -> Result<Vec<u8>, E>,

Decrypt the ciphertext value with an AEAD, using cipher to decrypt the cipher text and combined AAD as per RFC 8152 section 5.3.

Panics

This function will panic if no ciphertext is available. It will also panic if the context parameter does not refer to a recipient context.

Trait Implementations

impl AsCborValue for CoseRecipient

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 CoseRecipient

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 CoseRecipient

fn clone(&self) -> CoseRecipient

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CoseRecipient

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

Formats the value using the given formatter.

impl Default for CoseRecipient

fn default() -> CoseRecipient

Returns the “default value” for a type.

impl PartialEq<CoseRecipient> for CoseRecipient

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

This method tests for self and other values to be equal, and is used by ==.

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

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