Ansible Vault is a feature of Ansible that allows you to encrypt sensitive data such as passwords or keys in encrypted files, rather than as plaintext in playbooks or roles. This provides the ability to secure any sensitive data that is necessary to successfully run Ansible projects. Ansible Vault uses the AES 256 algorithm to provide symmetric encryption, which means that it uses the same password for encrypting and decrypting files. The ansible-vault command is the main interface for managing encrypted content within Ansible, and it is used to initially encrypt files and subsequently used to view, edit, or decrypt the data. Ansible Vault is especially useful if you have confidential data that you want to secure and prevent from being publicly exposed.
