Functions

func Decrypt

func Decrypt(buf []byte, key []byte) ([]byte, error)

Decrypt decrypts buf using key with AES-GCM AEAD mode.

func Encrypt

func Encrypt(buf []byte, key []byte) ([]byte, error)

Encrypt encrypts buf using key with AES-GCM AEAD mode, nonce is prepended to encrypted text and result is hex encoded.

func HandleWithEncryption

func HandleWithEncryption(provider secretProvider, handler http.Handler) http.HandlerFunc

HandleWithEncryption returns a http handler function that encrypts content returned by handler using key provided by secretProvider.

func Sign

func Sign(privateKey *ecdsa.PrivateKey, message string) (string, error)

Sign signs a message with an ECDSA private key. Returns signature in 0x string format.

func SignWithTimestamp

func SignWithTimestamp(privateKey *ecdsa.PrivateKey, message string) (string, string, error)

SignWithTimestamp signs a message with an ECDSA private key. Returns signature in 0x string format.

func ValidateSignedMessage

func ValidateSignedMessage(message string, signature string) (common.Address, error)

ValidateSignedMessage validates a signed message and returns wallet address from signature. Expects signature in 0x string format (hex).

Deprecated: ValidateSignedMessage is half-broken, as it does not check that the signature matches the message. You instead have to rely on checking the returned address matches the expected one. Use VerifySignedMessage instead.

func VerifySignedMessage

func VerifySignedMessage(publicKey *ecdsa.PublicKey, message, signature string) (common.Address, error)

VerifySignedMessage verifies a signed message against a public key and returns matching wallet address. Expects signature in 0x string format (hex).

Types

type HagallSecretProvider

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

A secret provider using Hagall token from HDS client.

func NewHagallSecretProvider

func NewHagallSecretProvider(client hdsClient) HagallSecretProvider

Returns a new HagallSecretProvider.

func (HagallSecretProvider) GetKey

func (h HagallSecretProvider) GetKey() ([]byte, error)

GetKey generates a 256-bit key using sha256 hash of Hagall secret with cache.
