sqrl

Go client and server implementation of the Secure QR Login (SQRL) protocol. See https://www.grc.com/sqrl/sqrl.htm for more information regarding SQRL.

Server implementation has a AuthHandler to verify signatures generated by https://github.com/geir54/android-sqrl

func Xor(a, b []byte)

Xor sets a equal to a XOR b.

Types ¶

type Client ¶

type Client struct {
}

func (*Client) Authenticate ¶

func (this *Client) Authenticate(id *Identity, password, siteUrl string, options Option) (request *http.Request, err error)

Authenticate

type Identity ¶

type Identity struct {
	*Key
	Check   [checkLen]byte
	Salt    [saltLen]byte
	N, R, P int
}

func (*Identity) Authenticate ¶

func (this *Identity) Authenticate(key *Key) bool

func (*Identity) ChangePassword ¶

func (this *Identity) ChangePassword(old, new string) (ok bool, err error)

ChangePassword

type Key ¶

type Key [keyLen]byte

Key represents a 256-bit cryptographic key.

func DeriveKey ¶

func DeriveKey(password, salt []byte, N, r, p, n int) (key *Key, err error)

func (*Key) DomainKey ¶

func (k *Key) DomainKey(domain string) (key *Key)

DomainKey returns the private key for domain. HMAC-SHA256 using k as the key and domain as the message to generate the 256-bit private key.

func (*Key) Hash ¶

func (k *Key) Hash() []byte

Hash returns the SHA256 hash

func (*Key) PublicKey ¶

func (k *Key) PublicKey() *Key

PublicKey returns the corresponding public key.

func (*Key) Sign ¶

func (k *Key) Sign(msg []byte) (sig *Signature)

Sign returns the cryptographic signature of the []byte msg.

func (*Key) Verify ¶

func (k *Key) Verify(msg []byte, sig *Signature) bool

Verify returns true if the cryptographic signature sig.

func (*Key) Xor ¶
