Django Simple Captcha

Available Generators

The following generators are available:

Random chars

Classic captcha that picks four random chars. This is case insensitive.

CAPTCHA_CHALLENGE_FUNCT = 'captcha.helpers.random_char_challenge'

Simple Math

Another classic, that challenges the user to resolve a simple math challenge by randomly picking two numbers between one and nine, and a random operator among plus, minus, times.

CAPTCHA_CHALLENGE_FUNCT = 'captcha.helpers.math_challenge'

Dictionary Word

Picks a random word from a dictionary file. Note, you must define CAPTCHA_WORDS_DICTIONARY in CaptchaConfiguration to use this generator.

CAPTCHA_CHALLENGE_FUNCT = 'captcha.helpers.word_challenge'

Roll your own

To have your own challenge generator, simply point CAPTCHA_CHALLENGE_FUNCT to a function that returns a tuple of strings: the first one (the challenge) will be rendered in the captcha, the second is the valid response to the challenge, e.g. ('5+10=', '15'), ('AAAA', 'aaaa')

Sample generator that returns six random digits:

def random_digit_challenge():
    import random
    ret = u''
    for i in range(6):
        ret += str(random.randint(0,9))
    return ret, ret
