Struct coset::CoseRecipientBuilder

pub struct CoseRecipientBuilder(_);

Builder for CoseRecipient objects.

Implementations

impl CoseRecipientBuilder

pub fn new() -> Self

Constructor for builder.

pub fn build(self) -> CoseRecipient

Build the completed object.

pub fn protected(self, protected: Header) -> Self

Set the associated field.

pub fn unprotected(self, unprotected: Header) -> Self

Set the associated field.

pub fn ciphertext(self, ciphertext: Vec<u8>) -> Self

Set the associated field.

pub fn add_recipient(self, recipient: CoseRecipient) -> Self

Add a CoseRecipient.

pub fn create_ciphertext<F>(
    self,
    context: EncryptionContext,
    plaintext: &[u8],
    external_aad: &[u8],
    cipher: F
) -> Self where
    F: FnOnce(&[u8], &[u8]) -> Vec<u8>, 

Calculate the ciphertext value, using cipher to generate the encrypted bytes from the plaintext and combined AAD (in that order). Any protected header values should be set before using this method.

Panics

This function will panic if the context parameter does not refer to a recipient context.

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

Calculate the ciphertext value, using cipher to generate the encrypted bytes from the plaintext and combined AAD (in that order). Any protected header values should be set before using this method.

Panics

This function will panic if the context parameter does not refer to a recipient context.

Trait Implementations

impl Default for CoseRecipientBuilder

fn default() -> CoseRecipientBuilder

Returns the “default value” for a type.
