Struct fernet::MultiFernet

pub struct MultiFernet { /* private fields */ }

Implementations

impl MultiFernet

MultiFernet encapsulates the encrypt operation with the first Fernet instance and decryption with the Fernet instances provided in order until successful decryption or a DecryptionError.

pub fn new(keys: Vec<Fernet>) -> MultiFernet

pub fn encrypt(&self, data: &[u8]) -> String

Encrypts data with the first Fernet instance. Returns a value (which is base64-encoded) that can be passed to MultiFernet::decrypt.

pub fn decrypt(&self, token: &str) -> Result<Vec<u8>, DecryptionError>

Decrypts a ciphertext, using the Fernet instances provided. Returns either Ok(plaintext) if decryption is successful or Err(DecryptionError) if no decryption was possible across the set of fernet keys.

Trait Implementations

impl Clone for MultiFernet

fn clone(&self) -> MultiFernet

Returns a copy of the value.

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

Performs copy-assignment from source.
