Functions

func GetAESPrefixTransformer

func GetAESPrefixTransformer(config *AESConfig) (value.PrefixTransformer, error)

GetAESPrefixTransformer returns a prefix transformer from the provided configuration

func GetPrefixTransformers

func GetPrefixTransformers(config *ResourceConfig) ([]value.PrefixTransformer, error)

GetPrefixTransformer constructs and returns the appropriate prefix transformers for the passed resource using its configuration

func GetTransformerOverrides

func GetTransformerOverrides(filepath string) (map[schema.GroupResource]value.Transformer, error)

GetTransformerOverrides returns the transformer overrides by reading and parsing the encryption provider configuration file

func ParseEncryptionConfiguration

func ParseEncryptionConfiguration(f io.Reader) (map[schema.GroupResource]value.Transformer, error)

ParseEncryptionConfiguration parses configuration data and returns the transformer overrides

Types

type AESConfig

type AESConfig struct {
	// keys is a list of keys to be used for creating the AES transformer.
	Keys []Key `json:"keys"`
}

AESConfig contains the API configuration for an AES transformer.

type EncryptionConfig

type EncryptionConfig struct {
	// kind is the type of configuration file.
	Kind string `json:"kind"`
	// apiVersion is the API version this file has to be parsed as.
	APIVersion string `json:"apiVersion"`
	// resources is a list containing resources, and their corresponding encryption providers.
	Resources []ResourceConfig `json:"resources"`
}

EncryptionConfig stores the complete configuration for encryption providers.

type IdentityConfig

type IdentityConfig struct{}

IdentityConfig is an empty struct to allow identity transformer in provider configuration.

type Key

type Key struct {
	// name is the name of the key to be used while storing data to disk.
	Name string `json:"name"`
	// secret is the actual AES key, encoded in base64. It has to be 16, 24 or 32 bytes long.
	Secret string `json:"secret"`
}

Key contains name and secret of the provided key for AES transformer.

type ProviderConfig

type ProviderConfig struct {
	// aes is the configuration for the AEAD-GCM transformer.
	AES *AESConfig `json:"aes,omitempty"`
	// identity is the (empty) configuration for the identity transformer.
	Identity *IdentityConfig `json:"identity,omitempty"`
}

ProviderConfig stores the provided configuration for an encryption provider.

type ResourceConfig

type ResourceConfig struct {
	// resources is a list of kubernetes resources which have to be encrypted.
	Resources []string `json:"resources"`
	// providers is a list of transformers to be used for reading and writing the resources to disk.
	// eg: aes, identity.
	Providers []ProviderConfig `json:"providers"`
}

ResourceConfig stores per resource configuration.
