func Decrypt(c Crypter, payload gather.Bytes, blobID blob.ID, output *gather.WriteBuffer) error

Decrypt decrypts the provided data using provided blobID to derive initialization vector.

func Encrypt(c Crypter, payload gather.Bytes, prefix, suffix blob.ID, output *gather.WriteBuffer) (blob.ID, error)

Encrypt encrypts the given data using crypter-defined key and returns a name that should be used to save the blob in the repository.

type Crypter interface {
	HashFunc() hashing.HashFunc
	Encryptor() encryption.Encryptor
}

Crypter ecapsulates hashing and encryption.

type StaticCrypter struct {
	Hash       hashing.HashFunc
	Encryption encryption.Encryptor
}

StaticCrypter implements Crypter interface with static hash and encryption functions.

func (p StaticCrypter) Encryptor() encryption.Encryptor

Encryptor returns the encryption algorithm.

func (p StaticCrypter) HashFunc() hashing.HashFunc

HashFunc returns the hashing algorithm.
