* status: new => needs_review
Comment:
The attached patch, which depends "somewhat" (`twist.py`) on #7110, adds
two challenge-response methods for new user registration:
* Simple question and answer, e.g., "How many bits are in one byte?"
* [http://recaptcha.net/ reCAPTCHA].
The code for both is in the new file `sagenb.notebook.challenge.py`. I've
also
* Rewritten `twist.RegistrationPage` for linearity.
* Modified `registration.html` and added the template `recaptcha.html`.
* Added several options to `sagenb.notebook.server_conf.defaults`:
{{{
#!python
defaults = {
[...]
'email': True,
'challenge': True,
'challenge_type': 'simple',
# 'challenge_type': 'recaptcha',
'recaptcha_public_key': '',
'recaptcha_private_key': '',
}
}}}
One way to test the "simple" challenge, after applying the patch:
* Backup `~/.sage`
* Delete `~/.sage`
* `sage`
* `sage: import sagenb.notebook.notebook_object as n;
n.notebook(accounts=True)`
* Enter admin's password twice.
* Browse to `http://localhost:8000`
* Log out, if necessary, and click on "Sign up for a new Sage Notebook
account".
* Try to sign up for new accounts.
To test the "recaptcha" challenge, [http://recaptcha.net/whyrecaptcha.html
sign up] for a [http://recaptcha.net/ reCAPTCHA] key, update
`server_conf.py`, and follow the steps above.
