Types

type StorageProtection

type StorageProtection interface {
	Protect(id string, input gather.Bytes, output *gather.WriteBuffer)
	Verify(id string, input gather.Bytes, output *gather.WriteBuffer) error
	OverheadBytes() int
}

StorageProtection encapsulates protection (HMAC and/or encryption) applied to local cache items.

func AuthenticatedEncryptionProtection

func AuthenticatedEncryptionProtection(key []byte) (StorageProtection, error)

AuthenticatedEncryptionProtection returns StorageProtection that protects cached data using authenticated encryption.

func ChecksumProtection

func ChecksumProtection(key []byte) StorageProtection

ChecksumProtection returns StorageProtection that protects cached data using HMAC checksums without encryption.

func NoProtection

func NoProtection() StorageProtection
