Types ¶
type AggregateSignature ¶
type AggregateSignature struct {
// contains filtered or unexported fields
}
AggregateSignature is a bls12-381 aggregate signature. The participants field contains the IDs of the replicas that participated in signature creation. This allows us to build an aggregated public key to verify the signature.
func Combine ¶
func Combine(sigs ...*PartialSignature) (*AggregateSignature, error)
Combine aggregates some partial signatures into a single aggregate signature.
func (*AggregateSignature) Clone ¶
func (s *AggregateSignature) Clone() *AggregateSignature
Clone returns a copy of the aggregate signature.
func (*AggregateSignature) FromBytes ¶
func (s *AggregateSignature) FromBytes(data []byte) (err error)
FromBytes unmarshals the aggregate signature from a byte slice.
func (*AggregateSignature) ToBytes ¶
func (s *AggregateSignature) ToBytes() ([]byte, error)
ToBytes marshals the aggregate signature to a byte slice.
func (*AggregateSignature) Verify ¶
func (s *AggregateSignature) Verify(qr quorum, msg []byte) error
AggregateVerify verifys if the aggregate signature is valid for the message.
type PartialSignature ¶
type PartialSignature struct {
// contains filtered or unexported fields
}
PartialSignature is a bls12-381 partial signature. it contains the ID of the replicas that signs this signature.
func (*PartialSignature) FromBytes ¶
func (s *PartialSignature) FromBytes(data []byte) (err error)
FromBytes unmarshals the partial signature from a byte slice.
func (*PartialSignature) ID ¶
func (s *PartialSignature) ID() common.ID
ID returns the id of signer.
func (*PartialSignature) ToBytes ¶
func (s *PartialSignature) ToBytes() ([]byte, error)
ToBytes marshals the partial signature to a byte slice.
func (*PartialSignature) Verify ¶
func (s *PartialSignature) Verify(qr quorum, msg []byte) error
Verify verifys if the partial signature is valid for the message.
type PartialSignatureSet ¶
type PartialSignatureSet []*PartialSignature
func (PartialSignatureSet) Len ¶
func (set PartialSignatureSet) Len() int
func (PartialSignatureSet) Less ¶
func (set PartialSignatureSet) Less(i, j int) bool
func (PartialSignatureSet) Swap ¶
func (set PartialSignatureSet) Swap(i, j int)
type PrivateKey ¶
type PrivateKey struct {
// contains filtered or unexported fields
}
PrivateKey is a bls12-381 private key.
func GeneratePrivateKey ¶
func GeneratePrivateKey() *PrivateKey
GeneratePrivateKey generates a random private key.
func (*PrivateKey) FromBytes ¶
func (k *PrivateKey) FromBytes(b []byte)
FromBytes unmarshals the private key from a byte slice.
func (*PrivateKey) Public ¶
func (k *PrivateKey) Public() *PublicKey
Public returns the public key associated with this private key.
func (*PrivateKey) SignWithId ¶
func (k *PrivateKey) SignWithId(msg []byte, id common.ID) (*PartialSignature, error)
SignWithId signs the message and generates a partial signature based on the ID.
func (PrivateKey) ToBytes ¶
func (k PrivateKey) ToBytes() []byte
ToBytes marshals the private key to a byte slice.
type PublicKey ¶
type PublicKey struct {
// contains filtered or unexported fields
}
PublicKey is a bls12-381 public key.
