![]() ![]() Please note that the credit field is not always included, and that absence of a False credit flag does not guarantee credit was earned. (See /enterprise for details on hCaptcha Enterprise features like bot scores, passive and nearly passive "No-CAPTCHA" modes, and more.) The must be loaded via HTTPS and can be placed anywhere on the page. First, you must include the hCaptcha javascript resource somewhere in your HTML page. HCaptcha requires two small pieces of client side code to render a captcha widget on an HTML page. ![]() unsafe-eval and unsafe-inline should include, Add the hCaptcha Widget to your Webpage #.If you are an enterprise customer and would like to enable additional verification to be performed, you can optionally choose the following CSP strategy: ![]() connect-src should include, Please do not hard-code specific subdomains, like, into your CSP: asset subdomains used may vary over time or by region.If you use CSP headers, please add the following to your configuration: Your Server->User: Session authorized, proceedĬontent Security Policy (CSP) headers are an added layer of security that help to mitigate certain types of attacks, including Cross Site Scripting (XSS), clickjacking, and data injection attacks. HCaptcha Siteverify->Your Server: Passcode is valid (success is true) Your Server->hCaptcha Siteverify: Is this passcode valid? Your Website or App->Your Server: Form or XHR with hCaptcha passcode HCaptcha Client API->Your Website or App: Passcode embedded in form or returned via JS/callback HCaptcha Client API->User: Returns challenge or passcode User->hCaptcha Client API: Please issue passcode Your Website or App->User: Load hCaptcha JS or SDK User->Your Website or App: Load Website or App Your server now knows the user is not a bot and lets them log in. hCaptcha says it is valid and credits your account. Your server then checks that passcode with the hCaptcha server API. When the user clicks Submit the passcode is sent to your server in the form. They get a passcode from our server that is embedded in your form. You embed the hCaptcha widget on your site. Custom data attributes like theme, size, and tab-index are also supported in the same way by hCaptcha. hCaptcha methods are API-compatible with reCAPTCHA methods, for example render() and onload(). If you're already using Google's reCAPTCHA, you can use your existing code with a few slight changes. To make integration even quicker, wrappers and plugins are available for many frameworks: Angular, Node, Express, ReactJS, VueJS, WordPress and more.Ī complete list of known hCaptcha integrations is also available. It requires either adding some simple HTML and server side code, or using one of the many tools that natively support hCaptcha. Using UUIDs is a good idea in brand new projects, but it might be wise to avoid transferring to UUIDs in a running production system unless you have a good reason to do so.The hCaptcha widget can protect your applications from bots, spam, and other forms of automated abuse. You can no longer assume the ‘highest’ id is the most recent, which could be confusing for new developers to your codebase. MySQL is a more complicated proposition and I wouldn’t bother.ĪctiveRecord’s first and last scopes work in an unexpected way with UUID ids. If you’re using PostgreSQL this is a straightforward change and has little performance cost. This is a case where you are making a choice toward a little more complexity, but for good reasons. You can get round this by generating ‘public ids’ or ‘slugs’ for exposed URLs… but then, why not use a built-in tool?įrom a security perspective, using UUIDs prevents the situation where a malicious attacker could attempt to gain access to data by guessing a model id in your URLs. With UUIDs no-one can guess the size of your database tables, which might be information you are keen to keep secret. With an incrementing integer id the size of your data can be inferred from the outside i.e. The UUIDs are globally unique meaning you can know that different models cannot possibly have the same id and you can even assign them client-side or in other systems. Using UUIDs as the id in your Rails models instead of incrementing integers helps you avoid collisions. references :other, type: :uuid, index: true end end end But why?
