 - `IMPORT_LOCAL_PATHS`: **false**: Set to `false` to prevent all users (including admin) from importing local path on server.
 - `INTERNAL_TOKEN`: **\<random at every install if no uri set\>**: Secret used to validate communication within Gitea binary.
 - `INTERNAL_TOKEN_URI`: **<empty>**: Instead of defining INTERNAL_TOKEN in the configuration, this configuration option can be used to give Gitea a path to a file that contains the internal token (example value: `file:/etc/gitea/internal_token`)

+  - Note: The default parameters for `pbkdf2` hashing have changed - the previous settings are available as `pbkdf2_v1` but are not recommended.
+  - The hash functions may be tuned by using `$` after the algorithm:

 - `CSRF_COOKIE_HTTP_ONLY`: **true**: Set false to allow JavaScript to read CSRF cookie.
 - `MIN_PASSWORD_LENGTH`: **6**: Minimum password length for new users.
 - `PASSWORD_COMPLEXITY`: **off**: Comma separated list of character classes required to pass minimum complexity. If left empty or no valid values are specified, checking is disabled (off):
