keychain_access

If you're a developer or someone who works with macOS's Keychain often, you might find keychain_access to be a helpful tool. This command-line software aims to provide users with keychain features in an accessible and convenient way. While Apple's security(1) command does some of this work, it falls short when it comes to accessing private/public key pairs stored in the Keychain.

Fortunately, keychain_access fills this gap and provides users with a way to access their private/public key pairs without compromising on the security of their system. This tool is particularly helpful for signing files for Sparkles appcast without having to authenticate each time you run a command. Additionally, you don't have to worry about your private key being stored in plaintext on your hard drive, making this a safer and more secure way to use your Keychain.

If you're interested in trying keychain_access out for yourself, it's worth noting that it is distributed and licensed under the terms of the MIT License. This means that you can use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the software without restriction. So if you're looking for a powerful and secure way to access your Keychain from the command line, keychain_access might be worth checking out.
