The "keychain" command is a command-line utility available on Unix-based systems, including Linux and macOS. It is used to manage and handle keychains, which are secure containers for storing various types of sensitive information like passwords, private keys, certificates, and secure notes.
Keychains act as a secure vault to protect these sensitive data by encrypting them. The "keychain" command provides a way to create, manage, and interact with keychains, making it easier to handle and access these secure elements.
