Class AbstractSignature

An abstract representation of a crypto signature, associated with a specific signature scheme, e.g., Ed25519 or Secp256k1.

This class represents the product of signing a message directly from a PrivateKey and can be verified against a CryptoPublicKey.

Implementation - BCS

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:33

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:46

Implementation - Serialization

toString

toString(): string
Get the signature as a hex string with a 0x prefix e.g. 0x123456...

Returns string
The hex string representation of the signature.
Inherited from Signature.toString
- Defined in src/core/crypto/signature.ts:29

toUint8Array

toUint8Array(): Uint8Array
Get the raw signature bytes

Returns Uint8Array
Inherited from Signature.toUint8Array
- Defined in src/core/crypto/signature.ts:19

Constructors

constructor

new AbstractSignature(value: HexInput): AbstractSignature
Parameters

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:55
