Functions

func CreateClientHMAC

func CreateClientHMAC(sessionKey, encryptedKey []byte,
	h func() hash.Hash) []byte

CreateClientHMAC constructs an HMAC on the encrypted client key.

func GenerateBaseKey

func GenerateBaseKey(g *cyclic.Group, peerPubKey *cyclic.Int,
	ownPrivKey *cyclic.Int, h hash.Hash) *cyclic.Int

GenerateBaseKey generates a Base Key from DHKX using RSA Keys g is the group used in RSA peerPubKey is the RSA PublicKey of the peer ownPrivKey is the RSA PrivateKey of the caller h is the hash to be used on the DHKX sessionKey Returns base key to be used in CMIX

func SignWithTimestamp

func SignWithTimestamp(rand io.Reader, priv *rsa.PrivateKey,
	timestampNano int64, userPubKeyPem string) ([]byte, error)

SignWithTimestamp signs a hash of the timestamp and the user's public key

func VerifyClientHMAC

func VerifyClientHMAC(sessionKey, encryptedKey []byte,
	h func() hash.Hash, receivedHmac []byte) bool

VerifyClientHMAC checks if the hmac received matches the values received.

func VerifyWithTimestamp

func VerifyWithTimestamp(serverPubKey *rsa.PublicKey,
	timestampNano int64, userPubKeyPem string, sig []byte) error

VerifyWithTimestamp verifies the signature provided against serverPubKey and the digest of the timestamp ts and userPubKey
