Post subject: disable-spambots

Title: disable-spambots
Author: vlad77
Description: Prevents in the forum phpBB2 registration of spambots, and posting spam in messages without registration.
Version: 2.0.0
Note: This mod checks the time between opening the page with the form, and sending the form. Time is passed in a hidden field in an encrypted form, using the mcrypt library. Decrypt the time and thereby replace it without a key can not.
When using captcha, be sure to increase the scan time by about 10 seconds.

Based on mods "disable-spambots" by magenta, and "Block spambots in registration" by Porutchik.

I pay attention, at changes of a fashion, it is necessary to not give to send the form if after page opening has passed for example more than 24 hours. This is caused by the noise immunity of the function mcrypt_ecb(), with small changes to the encrypted message, the last characters are lost in the decrypted message, so the time of opening the page with the form is sort of transferred to several years ago.
