Crate fernet

Fernet provides symmetric-authenticated-encryption with an API that makes misusing it difficult. It is based on a public specification and there are interoperable implementations in Rust, Python, Ruby, Go, and Clojure.

Example

// Store `key` somewhere safe!
let key = fernet::Fernet::generate_key();
let fernet = fernet::Fernet::new(&key).unwrap();
let plaintext = b"my top secret message!";
let ciphertext = fernet.encrypt(plaintext);
let decrypted_plaintext = fernet.decrypt(&ciphertext);
assert_eq!(decrypted_plaintext.unwrap(), plaintext);

Structs

DecryptionError	This error is returned when fernet cannot decrypt the ciphertext for any reason.
