Struct SymmetricEncryption 

pub struct SymmetricEncryption { /* private fields */ }

Symmetric encryption using Fernet (Python cryptography.fernet compatible)

Implementations

impl SymmetricEncryption

pub fn new(key: Option<&str>) -> Result<Self>

Create with generated key, or use provided key (base64 URL-safe encoded)

pub fn generate_key(&mut self) -> Result<String>

Generate a new key and use it

pub fn sign(&self, data: &[u8]) -> Result<Vec<u8>>

Encrypt data (acts as “sign” in KeyCryptoPrimitive: encrypt-then-verify)

pub fn verify(&self, data: &[u8], signature: &[u8]) -> Result<bool>

Verify by decrypting and comparing to original data

pub fn encrypt(&self, plaintext: &str) -> Result<String>

Encrypt plaintext string, return base64 token as string

pub fn decrypt(&self, ciphertext: &str) -> Result<String>

Decrypt ciphertext token, return plaintext string

pub fn get_key(&self) -> &str

Return the key as string (base64)

Trait Implementations

impl Clone for SymmetricEncryption

fn clone(&self) -> SymmetricEncryption

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for SymmetricEncryption

fn default() -> Self

Returns the “default value” for a type.
