Tower 9.4 for Mac — SSH Signing

Table of Contents

SSH support has been one of the most requested features recently. Today, we are thrilled to announce that you can now sign commits or tags using your SSH key and connect your SSH keys with your User Profiles directly from Tower!

In Git, we utilize GPG and SSH to authenticate commits and tags, ensuring they were indeed made by the intended individuals. If you have previously benefited from Tower's GPG support, available since version 3.5, you'll feel right at home with the new SSH integration.

This update enables you to:

  • Set and manage your SSH keys
  • Sign commits and tags
  • Verify the authenticity of signed commits and tags

All of these capabilities are just a few clicks away! Let's take a closer look at these features.

💡 Don't have an SSH key yet? Check out our tutorials on how to set it up:

Set and Manage Your SSH Keys

You can effortlessly select, set, and switch SSH keys in Tower by navigating to the "Git Config" tab in the "Preferences" dialog. Additionally, you have the option to choose your "allowed signers" file from within this tab.

If you prefer, you can also add an SSH key to your profile by visiting the "User Profiles" tab.

Lastly, you can configure specific SSH settings for individual repositories by accessing the "Settings" item in the sidebar of any open project. This screen also provides the flexibility to select a different "allowed signers" file if required.
