bcsToBytes

bcsToBytes(): Uint8Array
Serializes a Serializable value to its BCS representation. This function is the TypeScript SDK equivalent of bcs::to_bytes in Move.

Returns Uint8Array
the BCS representation of the Serializable instance as a byte buffer.
Inherited from Signature.bcsToBytes
- Defined in src/bcs/serializer.ts:45

bcsToHex

bcsToHex(): Hex
Converts the BCS-serialized bytes of a value into a Hex instance. This function provides a Hex representation of the BCS-serialized data for easier handling and manipulation.

Returns Hex
A Hex instance with the BCS-serialized bytes loaded into its underlying Uint8Array.
Inherited from Signature.bcsToHex
- Defined in src/bcs/serializer.ts:58

Implementation - Serialization

constructor

new Secp256r1Signature(hexInput: HexInput): Secp256r1Signature
Create a new Signature instance from a Uint8Array or String.
Parameters
- hexInput: HexInput
  A HexInput (string or Uint8Array)
Returns Secp256r1Signature
Overrides Signature.constructor
- Defined in src/core/crypto/secp256r1.ts:437

`Static` `Readonly`LENGTH

LENGTH: 64

Secp256r1 ecdsa signatures are 256-bit.

serialize

serialize(serializer: Serializer): void
Serializes the data into a byte array using the provided serializer. This function is essential for converting data into a format suitable for transmission or storage.
Parameters
- serializer: Serializer
  The serializer instance used to convert the data.
Returns void
Overrides Signature.serialize
- Defined in src/core/crypto/secp256r1.ts:479

toString

toString(): string
Get the signature as a hex string with the 0x prefix.

Returns string
string representation of the signature
Overrides Signature.toString
- Defined in src/core/crypto/secp256r1.ts:467

toUint8Array

toUint8Array(): Uint8Array
Get the signature in bytes (Uint8Array).

Returns Uint8Array
Uint8Array representation of the signature
Overrides Signature.toUint8Array
- Defined in src/core/crypto/secp256r1.ts:456

`Static`deserialize

deserialize(deserializer: Deserializer): Secp256r1Signature
Deserializes a Secp256r1Signature from the provided deserializer. This function allows you to reconstruct a Secp256r1Signature object from its serialized byte representation.
Parameters
- deserializer: Deserializer
  The deserializer instance used to read the serialized data.
Returns Secp256r1Signature
- Defined in src/core/crypto/secp256r1.ts:491

Methods

toStringWithoutPrefix

toStringWithoutPrefix(): string
Returns the hex string representation of the Serializable value without the 0x prefix.

Returns string
the hex format as a string without 0x prefix.
Inherited from Signature.toStringWithoutPrefix
- Defined in src/bcs/serializer.ts:67
