To be more technical, the first “Client Hello” message that your browser sends in clear text to the website’s servers contains not only the SNI, but also the TLS version and an encryption algorithm. TLS stands for Transport Layer Security, which is a cryptographic protocol that provides end-to-end security for data sent over the Internet. What we’ve described above is how a TLS handshake works. For example, if you went to your internet provider couldn’t see what you were searching for, but they could see that you were using Google. But by that point, your internet provider already knows the name of the website you are visiting. Having received the Client Hello message, the server replies with some information known as “Server Hello” to complete the ‘handshake’ with the device.Īfter that first greeting, the data your browser exchanges with the server is encrypted, so that only you and the website can see what’s inside it. This, in turn, means that network operators, including your ISP, can see it. The first piece of information your browser communicates when establishing an encrypted connection to the website is known as “Client Hello.” Some information in Client Hello, such as SNI (Server Name Indication, which is a way for your browser to tell the server which website it wants to connect to), is not encrypted. That’s kind of how HTTPS, a default protocol that is used by over 84% of websites, works. But anyone can see who you are sending the letter to by looking at the address. No one can open the envelope and read your letter without breaking the seal. You seal the envelope and write their name and address on it. Imagine you are sending a letter to your friend. But is ECH the missing piece of the puzzle that will solve privacy and defeat censorship once and for all? As much as we would like it to, it is unlikely.Īnd before we pour some cold water on the excitement over ECH and its supposed invincibility to censors, copyright authorities, peeping toms, and other prying eyes, we need to take a step back and cover some basics. AdGuard’s ECH support works across all apps and browsers that AdGuard filters. At AdGuard, we have added ECH support in our Windows, Mac, and Android apps, because we believe in the technology’s potential to make browsing more private. We believe ECH is indeed a major element of Internet privacy, and the importance of its support by such major players as Mozilla, Chrome, and Cloudflare cannot be understated. 1.A cutting-edge technology that is “filling the privacy gap in our existing online security infrastructure” and that, if widely adopted, “might even solve privacy for good.” Sounds promising, right? That’s how Mozilla and Cloudflare describe Encrypted Client Hello (ECH), a protocol that encrypts the entire “hello” message or the first communication between your browser and a website’s server. If you're looking for ad-blocking software for your Android phone, there are a plethora of free, high-quality options. To find the best free ad blocker for android apps, you're probably searching for an app that can block ads in the browser rather than system-wide ad blocking (as explained above).
