Policies define exactly which secrets a client can access and which operations it can perform with them. The opposite isn't true: we can – and usually do – create a child token with restrictive policies Another key point about this relationship: When we invalidate a token, all child tokens, and their descendants are also invalidated. One is simply to encrypt sensitive info directly in the playbooks. A child token can have at most the same level of privileges it parent has. There are two possibilities to encrypt data with a vault. ![]() Unless told otherwise, tokens created by Vault will form a parent-child relationship. A set of associated Policies (see next section).What is Vault Obtaining the Vault Client Configuring the Vault Client Logging. ![]() Tokens have a few properties associated with them. Password and Secret Management with the Hashicorp Vault command line client. Thinking about building a password manager on top of Vault, but there are a few. All those mechanisms build on top of the basic token mechanism: once Vault validates our client, it will provide a token that we can then use to access other APIs. Password managers exchange multiple passwords for one root password. Secure, store and tightly control access to tokens, passwords, certificates, encryption keys for protecting secrets and other sensitive data using a UI, CLI, or. HashiCorp Vault creates complex encryption processes that are secured by additional authorization and authentication protocols. Vault also support other authentication mechanisms such as LDAP, JWT, TLS Certificates, among others. This isn't a problem, though, since we can later generate another root token using unseal keys. As a best practice, we should use this root token just to create other tokens with fewer privileges and then revoke it. This token is the equivalent as root superuser in Linux systems, so its use should be limited to a minimum. When initially installed, Vault automatically generates a “root token”. The simplest method uses Tokens, which are just strings sent on every API request using a special HTTP header. ![]() To access secrets in Vault a client needs to authenticate itself using one of the supported methods.
