Functions

func Decode

func Decode(s string) uint64

Decode decodes a base36-encoded string.

func DecodeToBytes

func DecodeToBytes(b string) []byte

DecodeToBytes decodes a base36 string to a byte slice, using alphabet.

func Encode

func Encode(value uint64) string

Encode encodes a number to base36.

func EncodeBytes

func EncodeBytes(b []byte) string

EncodeBytes encodes a byte slice to base36 string.

func EncodeBytesAsBytes

func EncodeBytesAsBytes(b []byte) []byte

EncodeBytesAsBytes encodes a byte slice to base36.

func GenerateKeypair

func GenerateKeypair() (PublicKeyStr, PrivateKeyStr, error)

GenerateKeypair generates a public and private keypair string

Types

type PrivateKey

type PrivateKey struct {
	D []byte
}

PrivateKey is a bytestream of data not converted to anything

func GenerateKey

func GenerateKey() (*PrivateKey, error)

GenerateKey generate a new random private key

func PrivateKeyFromString

func PrivateKeyFromString(private string) (*PrivateKey, error)

PrivateKeyFromString grabs a private key string and gives out a privatekey object

func (*PrivateKey) Decrypt

func (private *PrivateKey) Decrypt(data []byte) (decrypted []byte, err error)

Decrypt will provide a decryption mechanism for an arbitrary bytestream

func (*PrivateKey) Encrypt

func (private *PrivateKey) Encrypt(public *PublicKey, data []byte) (encrypted []byte, err error)

Encrypt will provide a encryption mechanism for an arbitrary bytestream

func (PrivateKey) GetPublicKey

func (private PrivateKey) GetPublicKey() PublicKey

GetPublicKey returns a PublicKey object from the key

func (PrivateKey) String

func (private PrivateKey) String() PrivateKeyStr

String marshaller for private key

type PrivateKeyStr

type PrivateKeyStr string

type PublicKey

type PublicKey struct {
	elliptic.Curve
	X, Y *big.Int
}

PublicKey has the curve and the X,Y.

func GetPublicKeyFromMessage

func GetPublicKeyFromMessage(msg []byte) *PublicKey

GetPublicKeyFromMessage is a helper function to extract first 32 bytes from a long message, and provide the sender public key of it

func PublicKeyFromString

func PublicKeyFromString(public PublicKeyStr) (*PublicKey, error)

PublicKeyFromString grabs a public key string and gives out a publickey object

func (PublicKey) String

func (key PublicKey) String() PublicKeyStr

String marshaller for public key

type PublicKeyStr

type PublicKeyStr string
