Struct TokenHash 

pub struct TokenHash(/* private fields */);

SHA-256 of a token. Comparison is constant-time.

Implementations

impl TokenHash

pub fn of(token: &str) -> Self

Hashes a token string without validating it.

pub fn from_presented(presented: &str) -> Option<Self>

Hashes a token presented by a client, or None if it cannot be a token we issued (wrong length or alphabet). Avoids a store lookup for garbage cookies.

pub const fn from_bytes(bytes: [u8; 32]) -> Self

Wraps raw hash bytes read from a store.

pub const fn as_bytes(&self) -> &[u8; 32]

Raw hash bytes, for stores.

pub fn to_hex(&self) -> String

Lowercase hex, for stores that key by string.

pub fn from_hex(hex: &str) -> Option<Self>

Parses TokenHash::to_hex output.
