The token is a 40-digit hexstring, calculated as a HMAC-SHA1.
In a traditional HMAC scenario, an attacker is unable to know or
influence the secret key, but can know or influence the message
and token. This scenario is slightly different (in particular
since the message sender is also the message recipient), but
sufficiently similar to use an HMAC. Benefits compared to a plain
SHA1 hash includes resistance against a length extension attack.
The HMAC key consists of the following values (known only to the
server and authorized users):
* per-application secret (the `app_instance_uuid` setting), without
which an attacker cannot counterfeit tokens
* hashed user password, invalidating the token upon password change
The HMAC message consists of the following values (potentially known
to an attacker):
* session ID (the anti-CSRF token), requiring an attacker to have
access to the browser session in which the token was created
* numeric user ID, limiting the token to a specific user (yet allowing
users to be renamed)
* user email address
* time of token issue (a Unix timestamp, to enable token expiration)
The key and message values are separated by NUL characters, which are
guaranteed not to occur in any of the values.
