WHAT IS THIS?

server.js creates local server + static onion address accessible through tor to use for lnurlp or lightning addresses. it includes CORS headers so it can be fetched from random pages like https://codepen.io/legalizemath/full/eYymQKb (from tor browser)

what it creates for me for example:

• lightning address: btc@arihg6tpnvs7qsjtklrybolhcdpjkwj5w4jaacx7flc6vzpiuy42puid.onion
• lnurl-pay code: LNURL1DP68GUP69UHKZUNFDPNNVARSDEM8XDM3WD48G6MVWFUKYMMVDP3KGUR2DDMK5DTHX34XZCTR0QMKVMRRXEM85URFW4UNGVNSW45KGTN0DE5K7M309EMK2MRV944KUMMHDCHKCMN4WFK8QTMZW33SGXWMMV
• lnurl: http://arihg6tpnvs7qsjtklrybolhcdpjkwj5w4jaacx7flc6vzpiuy42puid.onion/.well-known/lnurlp/btc
• static homepage: http://arihg6tpnvs7qsjtklrybolhcdpjkwj5w4jaacx7flc6vzpiuy42puid.onion

INFO

for speed just re-used my bos wrappers which means it needs globally installed balanceofsatoshis for lnd (npm i -g balanceofsatoshis)

# install tor if not yet, tor --version

    sudo apt install tor

# generate password hash with: tor --hash-password "password"

# password hash looks like 16:94D87DAEACD5274060844DAD7AAC00239BBA59C61455407034007C435F

# edit tor settings file (ctrl-x close, ctrl-y yes to save changes, enter to confirm file path), replace nano w/ whatever editor

    sudo nano /etc/tor/torrc # edit torrc file

# add following 2 lines (obviously replace hashed control password w/ output from tor --hash-password):

# ControlPort 39051 # this is for controlling tor service

# HashedControlPassword 16:94D87DAEACD5274060844DAD7AAC00239BBA59C61455407034007C435F

    sudo service tor restart

git clone https://github.com/legalizemath/tor-lnurl-lightningaddress.git torlnurl
cd torlnurl
npm install

edit server.js to set the control port if different

edit settings.json for password for control port, example just uses "password" and corresponding hash

run via

npm link balanceofsatoshis
node server.js
# or shortcut via: npm run start

ctrl-c to stop both local server and onion hiddenservice

Manually connecting to tor controller via telnet

# If local website/server listens at 0.0.0.0:7890, this is how you put it up on onion address while telnet or socket connection is active

# For it to stay after disconnecting from telnet have to use Flag=Detached and then later remove with DEL_ONION serviceId

    telnet 0.0.0.0 39051
    AUTHENTICATE "password"
    ADD_ONION NEW:BEST Port=80,0.0.0.0:7890

# it will respond with serviceId, which is onion address without .onion

# and PrivateKey which can be used to re-host @ identical serviceId later after you remove it via

    ADD_ONION ED25519-V3:privatekey
