Class Signature<C>

constructor

• new Signature<C extends Ciphersuite>(R: Element<C>, z: Scalar<C>): Signature<C>

  Create a new Signature.

  Type Parameters

  • C extends Ciphersuite

  Parameters

  • R: Element<C>

    The commitment to the signature nonce

  • z: Scalar<C>

    The response to the challenge

  Returns Signature<C>

Readonly InternalR

Readonly Internalz

getR

• getR(): Element<C>

  Get the commitment R to the signature nonce.

  Returns Element<C>

  The R component of the signature

getZ

• getZ(): Scalar<C>

  Get the response z to the challenge.

  Returns Scalar<C>

  The z component of the signature

StaticdefaultDeserialize

• defaultDeserialize<C extends Ciphersuite>(
      ciphersuite: C,
      bytes: Uint8Array,
  ): Signature<C>
  Internal

  Converts default-encoded bytes into a Signature.

  The default encoding is the serialized R point followed by the serialized z scalar.

  Type Parameters

  • C extends Ciphersuite

  Parameters

  • ciphersuite: C

    The ciphersuite to use for deserialization

  • bytes: Uint8Array

    The serialized signature bytes

  Returns Signature<C>

  The deserialized Signature

  Throws

  If the signature encoding is malformed

Staticdeserialize

• deserialize<C extends Ciphersuite>(
      ciphersuite: C,
      bytes: Uint8Array,
  ): Signature<C>

  Converts bytes into a Signature using the ciphersuite's deserialization method.

  Type Parameters

  • C extends Ciphersuite

  Parameters

  • ciphersuite: C

    The ciphersuite to use for deserialization

  • bytes: Uint8Array

    The serialized signature bytes

  Returns Signature<C>

  The deserialized Signature

  Throws

  If the signature encoding is malformed

defaultSerialize

• defaultSerialize(ciphersuite: C): Uint8Array
  Internal

  Converts this signature to its default byte serialization.

  The default encoding is the serialized R point followed by the serialized z scalar.

  Parameters

  • ciphersuite: C

    The ciphersuite to use for serialization

  Returns Uint8Array

  The serialized signature as bytes

  Throws

  If serialization fails (e.g., R is the identity)

serialize

• serialize(ciphersuite: C): Uint8Array

  Converts this signature to its byte serialization using the ciphersuite's method.

  Parameters

  • ciphersuite: C

    The ciphersuite to use for serialization

  Returns Uint8Array

  The serialized signature as bytes

  Throws

  If serialization fails

equals

• equals(ciphersuite: C, other: Signature<C>): boolean

  Check equality with another Signature.

  Parameters

  • ciphersuite: C

    The ciphersuite to use for comparison

  • other: Signature<C>

    The other Signature to compare with

  Returns boolean

  True if the signatures are equal

clone

• clone(): Signature<C>

  Clone this Signature.

  Returns Signature<C>

  A new Signature with the same R and z values

toString

• toString(ciphersuite: C): string

  Convert to a debug string representation.

  Parameters

  • ciphersuite: C

    The ciphersuite to use for serialization

  Returns string

  A debug string showing R and z as hex
