Functions ¶
func CreateAddress ¶
Creates an ethereum address given the bytes and the nonce
func FromECDSA ¶
func FromECDSA(prv *ecdsa.PrivateKey) []byte
func FromECDSAPub ¶
func GenerateKey ¶
func GenerateKey() (*ecdsa.PrivateKey, error)
func HexToECDSA ¶
func HexToECDSA(hexkey string) (*ecdsa.PrivateKey, error)
HexToECDSA parses a secp256k1 private key.
func ImportBlockTestKey ¶
Used only by block tests.
func LoadECDSA ¶
func LoadECDSA(file string) (*ecdsa.PrivateKey, error)
LoadECDSA loads a secp256k1 private key from the given file. The key data is expected to be hex-encoded.
func PKCS7Unpad ¶
func SaveECDSA ¶
func SaveECDSA(file string, key *ecdsa.PrivateKey) error
SaveECDSA saves a secp256k1 private key to the given file with restrictive permissions. The key data is saved hex-encoded.
func ToECDSA ¶
func ToECDSA(prv []byte) *ecdsa.PrivateKey
New methods using proper ecdsa keys from the stdlib
func ToECDSAPub ¶
Types ¶
type BitCurve ¶
type BitCurve struct {
P *big.Int // the order of the underlying field
N *big.Int // the order of the base point
B *big.Int // the constant of the BitCurve equation
Gx, Gy *big.Int // (x,y) of the base point
BitSize int // the size of the underlying field
}
A BitCurve represents a Koblitz Curve with a=0. See http://www.hyperelliptic.org/EFD/g1p/auto-shortw.html
func S160 ¶
func S160() *BitCurve
S160 returns a BitCurve which implements secp160k1 (see SEC 2 section 2.4.1)
func S192 ¶
func S192() *BitCurve
S192 returns a BitCurve which implements secp192k1 (see SEC 2 section 2.5.1)
func S224 ¶
func S224() *BitCurve
S224 returns a BitCurve which implements secp224k1 (see SEC 2 section 2.6.1)
func S256 ¶
func S256() *BitCurve
S256 returns a BitCurve which implements secp256k1 (see SEC 2 section 2.7.1)
func (*BitCurve) GenerateKey ¶
TODO: double check if it is okay GenerateKey returns a public/private key pair. The private key is generated using the given reader, which must return random data.
func (*BitCurve) Marshal ¶
Marshal converts a point into the form specified in section 4.3.6 of ANSI X9.62.
func (*BitCurve) Params ¶
func (BitCurve *BitCurve) Params() *elliptic.CurveParams
func (*BitCurve) ScalarBaseMult ¶
ScalarBaseMult returns k*G, where G is the base point of the group and k is an integer in big-endian form.
func (*BitCurve) ScalarMult ¶
TODO: double check if it is okay ScalarMult returns k*(Bx,By) where k is a number in big-endian form.
type Key ¶
type Key struct {
Id uuid.UUID // Version 4 "random" for unique id not derived from key data
// to simplify lookups we also store the address
Address common.Address
// we only store privkey as pubkey/address can be derived from it
// privkey in this struct is always in plaintext
PrivateKey *ecdsa.PrivateKey
}
func GenerateNewKeyDefault ¶
func ImportPreSaleKey ¶
creates a Key and stores that in the given KeyStore by decrypting a presale key JSON
func NewKeyFromECDSA ¶
func NewKeyFromECDSA(privateKeyECDSA *ecdsa.PrivateKey) *Key
func (*Key) MarshalJSON ¶
func (*Key) UnmarshalJSON ¶
type KeyStore ¶
type KeyStore interface {
// create new key using io.Reader entropy source and optionally using auth string
GenerateNewKey(io.Reader, string) (*Key, error)
GetKey(common.Address, string) (*Key, error) // get key from addr and auth string
GetKeyAddresses() ([]common.Address, error) // get all addresses
StoreKey(*Key, string) error // store key optionally using auth string
DeleteKey(common.Address, string) error // delete key by addr and auth string
Cleanup(keyAddr common.Address) (err error)
}
