Methods of Signing Git Commits on MacOS

Last updated March 13, 2024

This Gist explains how to sign commits using gpg in a step-by-step fashion. Previously, krypt.co was heavily mentioned, but I've only recently learned they were acquired by Akamai and no longer update their previous free products. Those mentions have been removed.

Additionally, 1Password now supports signing Git commits with SSH keys and makes it pretty easy-plus you can easily configure Git Tower to use it for both signing and ssh.

For using a GUI-based GIT tool such as Tower or Github Desktop, follow the steps here for signing your commits with GPG.

EthMan uses raw TCP/IP connections (not HTTP) for remote management and statistics. Optionally, "psw" field is added to requests is the password for remote management is set for miner. The following commands are available (JSON format):

REQUEST: {"id":0,"jsonrpc":"2.0","method":"miner_getstat1"}

RESPONSE:

DEPRECATED

This library is now deprecated in favour of a more complete and SwiftUI friendly TextEditor backport:
