HashCash
Captcha - HashCash doesn't have too many features, but the extensible feature it does have is very powerful. Bot detection and reporting.
- Extension Page: Captcha - HashCash
The Captcha - HashCash plugin (v5.4.1+) for Joomla provides five hashing algorithms to power its invisible proof-of-work (PoW) system. This privacy-focused tool blocks bots and spam on forms such as contact pages, registrations, and comments. It avoids visible puzzles or third-party trackers. The plugin runs computations in the user's browser using JavaScript and the Web Crypto API. Humans experience smooth interactions. Automated attacks face high costs.
Forget bots vanishing after a failed attack. With Captcha - HashCash’s latest feature, every stumble turns into a clue you can track and outsmart. This isn’t just a CAPTCHA—it’s a bot-hunting machine that transforms your Joomla forms into a security goldmine. Imagine knowing who’s attacking, how they’re doing it, and where they’re hitting—all without bothering your users. That’s Detection Profiling, and it’s your key to staying ahead.
