The base trait that allows a developer to add CSRF protection to an application.

Required methods

Given a nonce and a time to live (TTL), create a cookie to send to the end user.

fn generate_token(&self, token_value: &[u8; 64]) -> Result<CsrfToken, CsrfError>

Given a nonce, create a token to send to the end user.

Given a decoded byte array, deserialize, decrypt, and verify the cookie.

fn parse_token(&self, token: &[u8]) -> Result<UnencryptedCsrfToken, CsrfError>

Given a decoded byte array, deserialize, decrypt, and verify the token.

Provided methods

fn verify_token_pair(
    &self,
    token: &UnencryptedCsrfToken,
    cookie: &UnencryptedCsrfCookie
) -> bool

Given a token pair that has been parsed, decoded, decrypted, and verified, return whether or not the token matches the cookie and they have not expired.

fn random_bytes(&self, buf: &mut [u8]) -> Result<(), CsrfError>

Given a buffer, fill it with random bytes or error if this is not possible.

fn generate_token_pair(
    &self,
    previous_token_value: Option<&[u8; 64]>,
    ttl_seconds: i64
) -> Result<(CsrfToken, CsrfCookie), CsrfError>

Given an optional previous token and a TTL, generate a matching token and cookie pair.
