Struct Token 

pub struct Token { /* private fields */ }

Implementations

impl Token

pub fn new(key: &[u8]) -> Result<Self, TokenError>

pub fn encrypt(&self, plaintext: &[u8], rng: &mut dyn Rng) -> Vec<u8>

pub fn encrypt_with_iv(&self, plaintext: &[u8], iv: &[u8; 16]) -> Vec<u8>

pub fn verify_hmac(&self, token: &[u8]) -> Result<bool, TokenError>

pub fn decrypt(&self, token: &[u8]) -> Result<Vec<u8>, TokenError>

pub fn decrypt_chunks( &self, chunks: &[&[u8]], skip: usize, ) -> Result<Vec<u8>, TokenError>

Decrypt a token that arrives as consecutive chunks, such as the parts of a resource, without joining them first. Each chunk is authenticated and decrypted while it is still in cache; nothing is returned unless the tag matches. The result is Token::decrypt of the joined bytes with its first skip bytes (at most one block) dropped, and the errors are the same, except that a plaintext shorter than skip is TokenError::DecryptionFailed.
