About
Cap is an open-source, self-hosted 
reCAPTCHA alternative that verifies visitors without visual puzzles, tracking, or third-party services.
It uses a two-layer verification model that combines proof-of-work challenges accelerated with 
WebAssembly and Web Workers, including SHA-256 hashing and optional GPU-resistant time-locks.
Cloudflare Email Address Obfuscation is a Cloudflare Scrape Shield security feature that encrypts email addresses in 
HTML to hide them from harvesting bots and keep them visible and clickable for human visitors.
It automatically detects and obfuscates visible email addresses, uses a non-render-blocking 
JavaScript decoder to restore them for human users, distinguishes bot and human traffic, and supports global or API toggling and exclusions for specific addresses or HTML tags.
