Functions

func GenerateKey 

func GenerateKey(rand io.Reader, params *Params) (*PrivateKey, *PublicKey, error)

GenerateKey Section 4.1.7. Algorithm 10: XMSS_keyGen - Generate an XMSS key pair Generates a XMSS key pair for a given parameter set. Format private: [(32bit) index || prvSeed || seed || pubSeed || root] Format public: [root || pubSeed]

func Verify 

func Verify(params *Params, publicKey *PublicKey, m, signature []byte) (match bool)

Verify Section 4.1.10. Algorithm 14: XMSS_verify - Verify an XMSS signature using the corresponding XMSS public key and a message Verifies a given message signature pair under a given public key. Note that this assumes a pk without an OID, i.e. [root || pubSeed]

Types

type Params 

type Params struct {
	// contains filtered or unexported fields
}

Params is a struct for parameters

func NewParams 

func NewParams(hashFunc func() hash.Hash, n, w, h, d, paddingLen int) *Params

func (*Params) Hash 

func (params *Params) Hash() hash.Hash

func (*Params) SignBytes 

func (params *Params) SignBytes() int

SignBytes the length of the signature based on a given parameter set

type PrivateKey 

type PrivateKey struct {
	D []byte
}

PrivateKey key

func (*PrivateKey) Equal 

func (priv *PrivateKey) Equal(x crypto.PrivateKey) bool

Equal reports whether priv and x have the same value.

func (*PrivateKey) PublicKey added in v1.0.2042 

func (priv *PrivateKey) PublicKey(params *Params) *PublicKey

func (*PrivateKey) Sign 

func (priv *PrivateKey) Sign(params *Params, m []byte) ([]byte, error)

Sign Section 4.1.9. Algorithm 12: XMSS_sign - Generate an XMSS signature and update the XMSS private key Signs a message. Returns an array containing the signature followed by the message and an updated secret key.

type PublicKey 

type PublicKey struct {
	X []byte
}

PublicKey key

func (*PublicKey) Equal 

func (pub *PublicKey) Equal(x crypto.PublicKey) bool

Equal reports whether pub and x have the same value.
