Versions:
HashiCorp Vault 1.21.4 is an enterprise-grade secrets-management platform that centralizes the storage, access control, and lifecycle of sensitive credentials such as API keys, database passwords, TLS certificates, and encryption keys. Designed for cloud-native and on-premises infrastructures alike, the application exposes a unified HTTP API and CLI through which operators can define fine-grained policies, rotate secrets automatically, generate dynamic credentials on demand, and maintain detailed audit trails. Typical use cases include injecting database credentials into CI/CD pipelines, delivering short-lived cloud access tokens to Kubernetes workloads, distributing TLS certificates to edge proxies, and encrypting application data without exposing raw keys. The software supports multiple pluggable backends—ranging in version count to 22 releases so far—allowing organizations to choose integrated storage like Consul, Raft, or cloud object stores, while offering optional sealing with HSMs or cloud KMS for added security. Additional capabilities include response wrapping, cubbyhole storage for temporary secrets, namespaces for multi-tenant isolation, and transforms for format-preserving encryption. Administrators can enable optional enterprise modules for namespaces replication, disaster recovery, and Sentinel policy-as-code governance. Vault is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
