Signs and verifies cookie values

Implementations

impl CookieSigner

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

key must be at least 32 bytes of randomness (see random_bytes)

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

An older key that still verifies cookies (key rotation)

pub fn sign(&self, name: &str, value: &str) -> String

value.signature, safe to use as a cookie value

pub fn verify(&self, name: &str, signed: &str) -> Option<String>

The original value if signed carries a valid signature for cookie name
