constructor

new SignatureImpl<C extends Ciphersuite>(
R: Element<C>,
z: Scalar<C>,
): SignatureImpl<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 SignatureImpl<C>
- Defined in core/dist/index.d.ts:2764

Methods

getR

getR(): Element<C>
Get the commitment R to the signature nonce.

Returns Element<C>
The R component of the signature
- Defined in core/dist/index.d.ts:2769

getZ

getZ(): Scalar<C>
Get the response z to the challenge.

Returns Scalar<C>
The z component of the signature
- Defined in core/dist/index.d.ts:2774

`Static`deserialize

deserialize<C extends Ciphersuite>(
ciphersuite: C,
bytes: Uint8Array,
): SignatureImpl<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 SignatureImpl<C>
The deserialized Signature

Throws
If the signature encoding is malformed
- Defined in core/dist/index.d.ts:2793

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
- Defined in core/dist/index.d.ts:2810

equals

equals(ciphersuite: C, other: SignatureImpl<C>): boolean
Check equality with another Signature.
Parameters
- ciphersuite: C
  The ciphersuite to use for comparison
- other: SignatureImpl<C>
  The other Signature to compare with
Returns boolean
True if the signatures are equal
- Defined in core/dist/index.d.ts:2817

clone

clone(): SignatureImpl<C>
Clone this Signature.

Returns SignatureImpl<C>
A new Signature with the same R and z values
- Defined in core/dist/index.d.ts:2822

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
- Defined in core/dist/index.d.ts:2828
