What is Vault (HashiCorp)?
A secrets management tool for securely storing, accessing, and rotating sensitive data.
HashiCorp Vault is a secrets management tool that provides secure storage and access control for sensitive data — API keys, passwords, certificates, encryption keys. Vault's killer feature is dynamic secrets: instead of storing long-lived credentials, Vault generates short-lived credentials on-demand (a database password valid for 1 hour, then expired). Vault integrates with Kubernetes, AWS, LDAP, and supports many auth methods. The External Secrets Operator syncs Vault secrets to K8s Secrets.
