SOPS is a command-line tool for managing encrypted secrets in configuration files. It encrypts and decrypts files in YAML, JSON, ENV, INI, and binary formats using cloud key management services or local encryption methods including AWS KMS, GCP KMS, Azure Key Vault, HuaweiCloud KMS, age, and PGP.
The tool solves the problem of storing sensitive data safely within version control systems and configuration repositories. Rather than requiring separate secret stores or manual encryption workflows, SOPS acts as an editor that transparently encrypts file contents while keeping the file structure readable. Users can edit encrypted files directly, and the tool handles encryption and decryption automatically. This approach allows secrets to live alongside configuration while remaining protected, and supports multiple encryption backends so teams can use their existing cloud infrastructure or local key management.
Teams managing infrastructure-as-code, Kubernetes deployments, or other configuration-heavy environments should consider SOPS when they need secrets integrated into their existing file-based workflows. It suits projects already using cloud key management services, as it integrates directly with those systems without requiring additional infrastructure. The tool is particularly valuable for teams that want encrypted secrets in version control without adopting a separate secrets management platform.
The project transitioned from Mozilla stewardship to a new group of maintainers under Cloud Native Computing Foundation sponsorship. Development shows active engagement with security practices, including a dedicated security advisory process for vulnerability reporting. The tool maintains broad compatibility across multiple encryption backends and file formats, indicating sustained effort to support diverse infrastructure environments and user preferences.
