Struct coset::CoseEncryptBuilder

pub struct CoseEncryptBuilder(_);

Builder for CoseEncrypt objects.

Implementations

impl CoseEncryptBuilder

pub fn new() -> Self

Constructor for builder.

pub fn build(self) -> CoseEncrypt

Build the completed object.

pub fn protected(self, hdr: 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 create_ciphertext<F>(
    self,
    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.

pub fn try_create_ciphertext<F, E>(
    self,
    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.

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

Add a CoseRecipient.

Trait Implementations

impl Debug for CoseEncryptBuilder

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

Formats the value using the given formatter.

impl Default for CoseEncryptBuilder

fn default() -> CoseEncryptBuilder

Returns the “default value” for a type.
