WebSocket Echo Server We run a free very simple endpoint server with support for websockets and server-sent events (SSE) so that you can test your websocket and SSE clients easily. The server is designed for testing HTTP proxies and clients. It echoes information about HTTP request headers and bodies back to the client. The endpoint is https://echo.websocket.org/ Behavior Any messages sent from a

We performed a large-scale study of RSA and DSA cryptographic keys in use on the Internet and discovered that significant numbers of keys are insecure due to insufficient randomness. These keys are being used to secure TLS (HTTPS) and SSH connections for hundreds of thousands of hosts. We found that 5.57% of TLS hosts and 9.60% of SSH hosts share public keys in an apparently vulnerable manner, due
Advisory: We only operate services from the RANDOM.ORG domain. Other sites that claim to be operated by us are impostors. If in doubt, contact us. What's this fuss about true randomness? Perhaps you have wondered how predictable machines like computers can generate randomness. In reality, most random numbers used in computer programs are pseudo-random, which means they are generated in a predictab
Here’s a little pre-Christmas treat – small tool that allows you to measure and analyze load time of any web page. It doesn’t require any changes in existing code, it shows also network and server side performance. And yes, it works with IE too. Click to see it work for this page Some time ago I came across this cool HTML5 Rocks article – Measuring Page Load Speed with Navigation Timing, that exp
JavaScript Required This site requires JavaScript, as well as the ability to pull in cross-site scripts, in order to perform the testing. If this message does not go away, it means that JavaScript has been disabled, either by a plugin or extension in your browser, or by explicit browser setting. Do you use NoScript? If you use this Firefox add-on, you'll need to "Temporarily allow all this page".

While we browse the web, most web pages have an interest in observing our behaviour in order to achieve certain business benefits. For example, they would like to know what kind of content the visitor is interested in, and, more specifically, what to recommend to a user who has already downloaded certain page(s) (e.g. article(s)). Therefore, vaguely knowing users’ areas of interest is often insuff

It's that last clause - the random injection - that makes the difference between simply crafting requests and basic fuzzing. Every time a new request is issued, the injection occurs at a different location. I varied the injected character between a NULL byte, a carriage return and a random alphabet letter. Each exposed different errors in different servers. For a complete description of the specif
Welcome to Taste Reports We provide daily updated domain tasting reports and detailed registrar statistics. Lists contain daily changes (yes, some registrars do register 100k+ domains!).
