Struct SealedMessage

pub struct SealedMessage { /* private fields */ }

A sealed message can be sent to anyone, but only the intended recipient can decrypt it.

Implementations

impl SealedMessage

pub fn new(plaintext: impl Into<Vec<u8>>, recipient: &dyn Encrypter) -> Self

Creates a new SealedMessage from the given plaintext and recipient.

pub fn new_with_aad( plaintext: impl Into<Vec<u8>>, recipient: &dyn Encrypter, aad: Option<impl Into<Vec<u8>>>, ) -> Self

Creates a new SealedMessage from the given plaintext, recipient, and additional authenticated data.

pub fn new_opt( plaintext: impl Into<Vec<u8>>, recipient: &dyn Encrypter, aad: Option<impl Into<Vec<u8>>>, test_key_material: Option<impl Into<Vec<u8>>>, test_nonce: Option<impl AsRef<Nonce>>, ) -> Self

Creates a new SealedMessage from the given plaintext, recipient, and additional authenticated data. Also accepts optional test key material and test nonce.

pub fn decrypt(&self, private_key: &PrivateKeyBase) -> Result<Vec<u8>, Error>

Decrypts the message using the recipient’s private key.

Trait Implementations

impl AsRef<SealedMessage> for SealedMessage

fn as_ref(&self) -> &SealedMessage

Converts this type into a shared reference of the (usually inferred) input type.

impl CBORTagged for SealedMessage

fn cbor_tags() -> Vec<Tag>

The CBOR tags assocated with this type. If more than one tag is present, they are considered equivalent for reading, but only the first one is used for writing.

impl CBORTaggedDecodable for SealedMessage

fn from_untagged_cbor(cbor: CBOR) -> Result<Self>

Creates an instance of this type by decoding it from untagged CBOR.

fn from_tagged_cbor(cbor: CBOR) -> Result<Self, Error>

where Self: Sized,

Creates an instance of this type by decoding it from tagged CBOR.

fn from_tagged_cbor_data(data: impl AsRef<[u8]>) -> Result<Self, Error>

where Self: Sized,

Creates an instance of this type by decoding it from binary encoded tagged CBOR.

fn from_untagged_cbor_data(data: impl AsRef<[u8]>) -> Result<Self, Error>

where Self: Sized,

Creates an instance of this type by decoding it from binary encoded untagged CBOR.

impl CBORTaggedEncodable for SealedMessage

fn untagged_cbor(&self) -> CBOR

Returns the untagged CBOR encoding of this instance.

fn tagged_cbor(&self) -> CBOR

Returns the tagged CBOR encoding of this instance.

fn tagged_cbor_data(&self) -> Vec<u8>

Returns the tagged value in CBOR binary representation.

impl Clone for SealedMessage

fn clone(&self) -> SealedMessage

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SealedMessage

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

Formats the value using the given formatter.

impl From<SealedMessage> for CBOR

fn from(value: SealedMessage) -> Self

Converts to this type from the input type.

impl PartialEq for SealedMessage

fn eq(&self, other: &SealedMessage) -> 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 TryFrom<CBOR> for SealedMessage

type Error = Error

The type returned in the event of a conversion error.

fn try_from(cbor: CBOR) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for SealedMessage
