Encrypt/Decrypt are AES-CTR without a MAC, so a stored ciphertext can be altered without detection. The only current caller derives a per-build key from the builder and runner IDs, which is fine for the short-lived build environment but cannot be used for values that outlive a process. Add Seal/Open on top of AES-256-GCM (base64(nonce|ciphertext|tag)) next to the existing helpers instead of changing them: the builder image still decrypts the CTR format with crypt.Decrypt. The key is derived with sha256 like Encrypt, so operators only deal with one key convention. Verification: - go test -tags "netgo,timetzdata,exclude_graphdriver_btrfs,containers_image_openpgp" ./pkg/utils/crypt/...

AI Clients and Automation
Sigma provides two integration paths for AI clients and external automation:
sigma-cli: a single binary that operates a remote Sigma server over the REST API. It covers namespaces, repositories, tags, artifacts, members, and users. See CLI & AI Agents.- External REST API skill:
tools/skill/sigma-api-operatorpackages a reusable skill andswagger.yamlso CLI agents such as Claude Code or Copilot CLI can discover Sigma APIs and operate resources through HTTP requests, including the areas the CLI does not wrap yet.
