Overview

Package stores acts as a layer between the internal representation of encrypted files and the encrypted files themselves.

Subpackages implement serialization and deserialization to multiple formats.

This package defines the structure SOPS files should have and conversions to and from the internal representation. Part of the purpose of this package is to make it easy to change the SOPS file format while remaining backwards-compatible.

Functions

func Flatten

func Flatten(in map[string]interface{}) map[string]interface{}

Flatten flattens a map with potentially nested maps into a flat map. Only string keys are allowed on both the top-level map and child maps.

func Unflatten

func Unflatten(in map[string]interface{}) map[string]interface{}

Unflatten unflattens a map flattened by Flatten

}

Metadata is stored in SOPS encrypted files, and it contains the information necessary to decrypt the file. This struct is just used for serialization, and SOPS uses another struct internally, sops.Metadata. It exists in order to allow the binary format to stay backwards compatible over time, but at the same time allow the internal representation SOPS uses to change over time.

func MetadataFromInternal

func MetadataFromInternal(sopsMetadata sops.Metadata) Metadata

MetadataFromInternal converts an internal SOPS metadata representation to a representation appropriate for storage

func (*Metadata) ToInternal

func (m *Metadata) ToInternal() (sops.Metadata, error)

ToInternal converts a storage-appropriate Metadata struct to a SOPS internal representation

type SopsFile

type SopsFile struct {
	// Metadata is a pointer so we can easily tell when the field is not present
	// in the SOPS file by checking for nil. This way we can show the user a
	// helpful error message indicating that the metadata wasn't found, instead
	// of showing a cryptic parsing error
	Metadata *Metadata `yaml:"sops" json:"sops" ini:"sops"`
}

SopsFile is a struct used by the stores as a helper to unmarshal the SOPS metadata
