GoKawiilAndroid 17 adds system-wide Encrypted Client Hello support
Google has built Encrypted Client Hello (ECH) directly into Android 17, making it the first major mobile operating system to support the standard at the platform level and turning it on by default. ECH hides the specific website or domain a device is connecting to, so internet providers can only see the content delivery network being used, not the actual destination. Alphabet's Jigsaw division, which developed the feature, says it addresses a long-standing gap in HTTPS privacy protections.
