Hashcash technology for Joomla Download

Description:

Forcing the spammer to pay the price (computing power) before submitting rubish to Your homepage (comments, guestbook for example). The user will have to create a new cryptographic value of a hidden field ( Javascript code provided ) and that may take 1 to 2 seconds, but may be more with RSA 1024.... This also do not allow robot to easily sumbit code without parsing Your HTML page before... Hashcash definition: A sender of non-spam posting attaches a hidden field from his post which proves that he has invested a modest amount of computer time into solving a small puzzle, often involving the recipient's email address. The receiver can, at negligible computational cost, verify that a sender had solved the puzzle. This can be regarded as a form of numerical stamp, where the 'cash' part is the effort invested by the sender. The theory is that spammers, whose business model relies on their ability to send large numbers of emails with very little cost per message, cannot afford this investment into each individual piece of spam they send. Receivers can verify whether a sender made such an investment and use the results to help filter email.
