Types

type MasterKey

type MasterKey struct {
	// Identities contains the set of Bench32-encoded age identities used to
	// Decrypt.
	// They are lazy-loaded using MasterKeyFromIdentities, or on first
	// Decrypt().
	// In addition to using this field, ParsedIdentities.ApplyToMasterKey() can
	// be used to parse and lazy-load identities.
	Identities []string
	// Recipient contains the Bench32-encoded age public key used to Encrypt.
	Recipient string
	// EncryptedKey contains the SOPS data key encrypted with age.
	EncryptedKey string
	// contains filtered or unexported fields
}

MasterKey is an age key used to Encrypt and Decrypt SOPS' data key.

Adapted from https://github.com/mozilla/sops/blob/v3.7.2/age/keysource.go to be able to have fine-grain control over the used decryption keys without relying on the existence of file(path)s.

func MasterKeyFromIdentities

func MasterKeyFromIdentities(identities ...string) (*MasterKey, error)

MasterKeyFromIdentities takes a set if Bech32-encoded age identities, parses them, and returns a new MasterKey.

func MasterKeyFromRecipient

func MasterKeyFromRecipient(recipient string) (*MasterKey, error)

MasterKeyFromRecipient takes a Bech32-encoded age public key, parses it, and returns a new MasterKey.

func (*MasterKey) Decrypt

func (key *MasterKey) Decrypt() ([]byte, error)

Decrypt decrypts the EncryptedKey with the (parsed) Identities and returns the result.

func (*MasterKey) Encrypt

func (key *MasterKey) Encrypt(dataKey []byte) error

Encrypt takes a SOPS data key, encrypts it with the Recipient, and stores the result in the EncryptedKey field.

func (*MasterKey) EncryptIfNeeded

func (key *MasterKey) EncryptIfNeeded(dataKey []byte) error

EncryptIfNeeded encrypts the provided SOPS data key, if it has not been encrypted yet.

func (*MasterKey) EncryptedDataKey

func (key *MasterKey) EncryptedDataKey() []byte

EncryptedDataKey returns the encrypted SOPS data key this master key holds.

func (*MasterKey) NeedsRotation

func (key *MasterKey) NeedsRotation() bool

NeedsRotation returns whether the data key needs to be rotated or not.

func (*MasterKey) SetEncryptedDataKey

func (key *MasterKey) SetEncryptedDataKey(enc []byte)

SetEncryptedDataKey sets the encrypted SOPS data key for this master key.

func (*MasterKey) ToMap

func (key *MasterKey) ToMap() map[string]interface{}

ToMap converts the MasterKey to a map for serialization purposes.

func (*MasterKey) ToString

func (key *MasterKey) ToString() string

ToString converts the key to a string representation.

type ParsedIdentities

type ParsedIdentities []age.Identity

ParsedIdentities contains a set of parsed age identities. It allows for creating a (local) keyservice.KeyServiceServer which parses identities only once, to then inject them using ApplyToMasterKey() for all requests.

func (ParsedIdentities) ApplyToMasterKey

func (i ParsedIdentities) ApplyToMasterKey(key *MasterKey)

ApplyToMasterKey configures the ParsedIdentities on the provided key.

func (*ParsedIdentities) Import

func (i *ParsedIdentities) Import(identity ...string) error

Import attempts to parse the given identities, to then add them to itself. It returns any parsing error. A single identity argument is allowed to be a multiline string containing multiple identities. Empty lines and lines starting with "#" are ignored. It is not thread safe, and parallel importing would better be done by parsing (using age.ParseIdentities) and appending to the slice yourself, in combination with e.g. a sync.Mutex.
