Overview ¶
Package encrypt defines the contract a state-file encrypter implements.
Encrypter values seal and unseal opaque byte slices. State backends receive an Encrypter from the runtime and call it once per snapshot read or write. The runtime uses the same encrypter for plan files. The implementations and the fixed set an operator selects from live together in pkg/encrypters.

Constants ¶
const ( ConfigKeyID = "key-id" ConfigEnvVar = "env-var" )
Well-known Description config keys. Each must match the name the config decoder derives from the key source's schema struct.

Types ¶
type Description ¶
Description identifies a key source and the configuration that builds the same encrypter again. KeySource is the registry name an operator selects in stack encryption. Config holds the configuration by operator-facing field name and must stay decodable against the key source's configuration schema. Key material never belongs in a Description: descriptions are written to disk in plaintext.
type Encrypter ¶
type Encrypter interface {
Encrypt(plaintext []byte) ([]byte, error)
Decrypt(ciphertext []byte) ([]byte, error)
// Describe reports which key source this encrypter is and the
// non-secret configuration a reader needs to decrypt what it
// sealed. Envelope sealing calls Describe after Encrypt, so the
// result may include facts resolved while encrypting, such as
// the kms encrypter's key ARN.
Describe() Description
}
Encrypter seals and unseals opaque bytes. Implementations cover one key source each: an env var holding a 32-byte symmetric key, a KMS service that wraps a per-snapshot data key, and so on.
type EncrypterType ¶
type EncrypterType struct {
Name string
Description string
Configuration *cfg.ConfigurationType
New func(config any, body map[string]any) (Encrypter, error)
}
EncrypterType registers one of the fixed set of state encrypters. Configuration describes the schema for the `encryption:` block fields the operator writes (e.g., env-var for the env-key encrypter). New is the factory the runtime invokes once it has decoded the configuration against that schema; body holds the same fields undecoded, keyed by operator-facing name, for encrypters that include them in their Description.
