JS AES encryption example

This is a quick example of how to get symmetric encryption in JS using [aes.js from the crypto-js project][1]:

// at this point http://crypto-js.googlecode.com/svn/tags/3.1.2/build/rollups/aes.js should be loaded

var data = 'a JSON blob or something',
    password = 'my long and very secretive passphrase';

var encrypted = CryptoJS.AES.encrypt(data, password).toString();

enabled = true
port = http,https
logpath = /var/log/nginx/access.log
maxretry = 3

Symmetic encryption

For symmetic encryption, you can use the following:

To encrypt:

openssl aes-256-cbc -salt -a -e -in plaintext.txt -out encrypted.txt

To decrypt:

Setting up geth as a service under systemd Fedora 27

Prerequisite: dnf install golang

1. Create user geth with useradd
2. As user geth fast sync the blockchain, geth --fast --cache 1024
3. Manually run geth --rpc as user geth and watch to see that the blockchain continues to sync properly
4. Install the geth.service file (also in this gist) in /usr/lib/systemd/system/
5. Make a symlink from /etc/systemd/system/multi-user.target.wants/geth.service to /usr/lib/systemd/system/geth.service
6. systemctl enable geth followed by systemctl start geth
