Functions ¶

func DeriveKey ¶

func DeriveKey(out []byte, secret *[32]byte, additional []byte)

DeriveKey uses the blake2b XOF to fill out. The input to the XOF is additional and secret is used to key the XOF.

func DeriveStream ¶

func DeriveStream(secret *[32]byte, additional []byte) io.Reader

DeriveStream returns a cryptographically secure psuedorandom stream derived from a high entropy secret, and arbitrary additional bytes.

func Equal ¶

func Equal(a, b Ref) bool

func Hash ¶

func Hash(x []byte) cadata.ID

func MarshalRef ¶

func MarshalRef(x Ref) []byte

Types ¶

type DEK ¶

type DEK [DEKSize]byte

func Convergent ¶

func Convergent(ptextHash cadata.ID) DEK

Convergent generates a DEK depending only on ptextHash

func (*DEK) String ¶

func (*DEK) String() string

type KeyFunc ¶

type KeyFunc func(ptextHash cadata.ID) DEK

KeyFunc produces a key for a given blob

func SaltedConvergent ¶

func SaltedConvergent(salt *[32]byte) KeyFunc
