Methods
impl Fernet[src]
Fernet encapsulates encrypt and decrypt operations for a particular key.
pub fn new(key: &str) -> Option<Fernet>[src]
Returns a new fernet instance with the provided key. The key should be
32-bytes, base64-encoded. Generating keys with Fernet::generate_key
is recommended. DO NOT USE A HUMAN READABLE PASSWORD AS A KEY. Returns
None if the key is not 32-bytes base64 encoded.
pub fn generate_key() -> String[src]
Generates a new, random, key. Can be safely passed to Fernet::new().
Store this somewhere safe!
pub fn encrypt(&self, data: &[u8]) -> String[src]
Encrypts data. Returns a value (which is base64-encoded) that can be
passed to Fernet::decrypt.
pub fn decrypt(&self, token: &str) -> Result<Vec<u8>, DecryptionError>[src]
Decrypts a ciphertext. Returns either Ok(plaintext) if decryption is
successful or Err(DecryptionError) if there are any errors.
