Struct coset::CoseEncrypt

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

Structure representing an encrypted object.

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

Fields

protected: ProtectedHeader

unprotected: Header

ciphertext: Option<Vec<u8>>

recipients: Vec<CoseRecipient>

Implementations

impl CoseEncrypt

pub fn decrypt<F, E>( &self, 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.

Panics

This function will panic if no ciphertext is available.

Trait Implementations

impl AsCborValue for CoseEncrypt

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 CoseEncrypt

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 CoseEncrypt

fn clone(&self) -> CoseEncrypt

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CoseEncrypt

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

Formats the value using the given formatter.

impl Default for CoseEncrypt

fn default() -> CoseEncrypt

Returns the “default value” for a type.

impl PartialEq<CoseEncrypt> for CoseEncrypt

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

impl TaggedCborSerializable for CoseEncrypt

const TAG: u64 = 96u64

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.
