Enable DNS over HTTPS and Encrypted SNI in Firefox January 2, 2019Security In Firefox 62, Mozilla has added two new features called DNS over HTTPS (DoH) and Trusted Recursive Resolver (TRR). The ideal behind each of these features is to improve user privacy and improved performance.

The ideal behind each of these features is to improve user privacy and improved performance. 2018-10-18 2020-03-05 2020-08-09 2019-04-08 The purpose of SNI encryption is to prevent that and aid privacy. Replacing cleartext SNI transmission by an encrypted variant will improve the privacy and reliability of TLS connections, but the design of proper SNI encryption solutions is difficult. In the past, there have been multiple attempts at defining SNI encryption. These The simplest SNI encryption designs replace in the initial TLS exchange the clear text SNI with an encrypted value, using a key known to the multiplexed server. Regardless of the encryption used, these designs can be broken by a simple replay attack, which works as follow: If the SNI is unencrypted and required to be always present, this scheme will work all the time.

But this idea was abandoned since this would require establishing an additional encryption layer and thus … This draft describes the general problem of encryption of the Server Name Identification (SNI) parameter. The proposed solutions hide a Hidden Service behind a Fronting Service, only disclosing the SNI of the Fronting Service to external observers. The draft lists known attacks against SNI encryption, discusses the current "co-tenancy fronting" solution, and presents requirements for future With the increasing use of TLS encryption over web traffic, censors start to deploy SNI filtering for more effective cen-sorship. Specifically, a censor can identify the web domain being accessed by a client via the SNI extension in the TLS ClientHello message. In response, in August 2018, a new ex- In this video we set up Encrypted SNI (ESNI) using advanced settings in Firefox. ESNI is a new encryption standard being championed by Cloudflare which allow Azure Application Gateway has end-to-end TLS encryption to support these requirements.

The draft lists known attacks against SNI encryption, discusses the current "co-tenancy fronting" solution, and presents requirements for future SNI is a technology that allows multiple web server to be hosted on the same IP and listening on the same port but use different SSL/TLS certificates for encryption. Before SNI two web servers listening on the same port had to share the certificate, for example having a reverse proxy handling the TLS channel and redirecting the traffic to the actual web-server At first glance, encrypted SNI—in whatever form it may eventually take—is a silver bullet. It's domain fronting without the downsides. It solves all our problems, up to traffic analysis: payload encryption prevents blocking by content, and SNI encryption protects the destination address. The censor cannot distinguish various connections One of the more difficult problems is "Do not stick out" (, Section 3.4): if only sensitive or private services use SNI encryption, then SNI encryption is a signal that a client is going to such a service.
