func BLSSignatureFromBytes ¶
func BLSSignatureFromBytes(data []byte) (result *BLSSignature, consumedBytes int, err error)
BLSSignatureFromBytes unmarshals a BLS signature from a sequence of bytes.
func NewBLSSignature ¶
func NewBLSSignature(pubKey, signature []byte) *BLSSignature
NewBLSSignature creates BLS signature from raw public key and signature data
func (*BLSSignature) Address ¶
func (sig *BLSSignature) Address() address.Address
Address returns the address that this signature signs.
func (*BLSSignature) Bytes ¶
func (sig *BLSSignature) Bytes() []byte
Bytes marshals the signature into a sequence of bytes.
func (*BLSSignature) IsValid ¶
func (sig *BLSSignature) IsValid(signedData []byte) bool
IsValid returns true if the signature correctly signs the given data.
func (*BLSSignature) PublicKeySize ¶
func (sig *BLSSignature) PublicKeySize() int
PublicKeySize returns the size of the public key.
func (*BLSSignature) SignatureSize ¶
func (sig *BLSSignature) SignatureSize() int
SignatureSize returns the size of the signature.
func (*BLSSignature) String ¶

type ED25519Signature ¶
type ED25519Signature struct {
// contains filtered or unexported fields
}
ED25519Signature represents a signature for an addresses that uses elliptic curve cryptography.
func Ed25519SignatureFromBytes ¶
func Ed25519SignatureFromBytes(bytes []byte, optionalTargetObject ...*ED25519Signature) (result *ED25519Signature, consumedBytes int, err error)
Ed25519SignatureFromBytes unmarshals an ed25519 signatures from a sequence of bytes. It either creates a new signature or fills the optionally provided object with the parsed information.
func (*ED25519Signature) Address ¶
func (signature *ED25519Signature) Address() address.Address
Address returns the address, that this signature signs.
func (*ED25519Signature) Bytes ¶
func (signature *ED25519Signature) Bytes() []byte
Bytes returns a marshaled version of the signature.
func (*ED25519Signature) IsValid ¶
func (signature *ED25519Signature) IsValid(signedData []byte) bool
IsValid returns true if the signature is valid for the given data.
func (*ED25519Signature) PublicKeySize ¶
func (signature *ED25519Signature) PublicKeySize() int
PublicKeySize returns the size of the public key.
func (*ED25519Signature) SignatureSize ¶
func (signature *ED25519Signature) SignatureSize() int
SignatureSize returns the size of the signature.
type Signature ¶
type Signature interface {
// IsValid returns true if the signature is valid for the given data.
IsValid(signedData []byte) bool
// Bytes returns a marshaled version of the signature.
Bytes() []byte
// Address returns the address that this signature signs.
Address() address.Address
// PublicKeySize returns the size of the public key.
PublicKeySize() int
// SignatureSize returns the size of the signature.
SignatureSize() int
}
Signature defines an interface for an address signature generated by the corresponding signature scheme.
func AggregateBLSSignatures ¶
AggregateBLSSignatures combined multiple Signatures into a single one.
type SignatureScheme ¶
type SignatureScheme interface {
// Version returns the version byte that is associated to this signature scheme.
Version() byte
// Address returns the address that this signature scheme instance is securing.
Address() address.Address
// Sign creates a valid signature for the given data according to the signature scheme implementation.
Sign(data []byte) Signature
}
SignatureScheme defines an interface for different signature generation methods (i.e. ED25519, WOTS, and so on ...).
func BLS ¶
func BLS(priKey, pubKey []byte) (SignatureScheme, error)
BLS creates an instance of BLS signature scheme from given private and public keys in marshaled binary form
func ED25519 ¶
func ED25519(keyPair ed25519.KeyPair) SignatureScheme
ED25519 creates an instance of a signature scheme, that is used to sign the corresponding address.
func RandBLS ¶
func RandBLS() SignatureScheme
RandBLS creates a RANDOM instance of a signature scheme, that is used to sign the corresponding address. only for testing: each time same sequence!
