Geth supporting SSL using reverse proxy server HD

At this moment Geth does not support SSL. A reverse proxy server can be used to access a Geth node by SSL. This video explains how to setup a very simple reverse proxy server. Prerequisites --------------------- To setup a reverse proxy server you need a SSL certificate. In this video a reverse proxy server will be setup for testing and development purpose. Therefore the SSL certificate does not need to be issued by a "real" Certificate Authority. A self signed SSL certificate will suffice. In this video I will be using an already created self signed SSL certificate. How I created my own self signed SSL certificate is explained in YouTube video: "Create self signed certificates with Subject Alternative Names" https://youtu.be/qoS4bLmstlk I assume you already have installed the node package manager. See: https://nodejs.org Problem description -------------------------------- A web application can access a local running Geth node using the web3.js library. Code to create an injected web3 instance: var web3 = new Web3(new Web3.providers.HttpProvider("http://localhost:8545")); But when the web application is secured (https) the Geth node can be accessed by http://localhost:8545 but you will get a warning message. Example: https://sand.mobilefish.com/download/ethereum/ethereum_show_all_accounts.html To solve the problem, the Geth node should be accessible by https://localhost:8545. However this is not possible, at least not in Geth v1.7 (maybe in the future?) Solution ------------- The solution is to setup a reverse proxy server. - Web app: https://sand.mobilefish.com/download/ethereum/ethereum_show_all_accounts.html Web3.providers.HttpProvider(“https://proxy.mobilefish.com:9070”) - Reverse proxy server: Listen: https://proxy.mobilefish.com:9070 Target: http://localhost:8545 - Geth node: http://localhost:8545 Setup reverse proxy server ------------------------------------------ The procedure described is also documented at: https://www.mobilefish.com/developer/blockchain/ blockchain_quickguide_geth_suppor t_ssl.html Check out all my other Ethereum related tutorial videos: https://goo.gl/eNJVXe Subscribe to my YouTube channel: https://goo.gl/61NFzK The presentation used in this video tutorial can be found at: https://www.mobilefish.com/developer/blockchain/blockchain_quickguide_ethereum_related_tutorials.html #mobilefish #howto #ethereum
