Disclaimer: Do not use the private key shown in this demo; it's public, strangers could steal your Eth. Never share your private key with anyone. It's your and only your responsibility to keep your private key in secret. Download the latest release here. To display usage, run ethaddrgen -h or ethaddrgen --help for a longer version. ethaddrgen expects the last arguments to be patterns. If no patterns are provided as arguments, ethaddrgen reads patterns from the standard input where each pattern is on a separate line.
