Constructors

constructor

new Secp256k1PrivateKey(hexInput): Secp256k1PrivateKey
Create a new PrivateKey instance from a Uint8Array or String.
Parameters
- hexInput: HexInput
  A HexInput (string or Uint8Array)
Returns Secp256k1PrivateKey
Overrides Serializable.constructor
- Defined in src/core/crypto/secp256k1.ts:111

Properties

`Private` `Readonly` key

key: Hex

The private key bytes

`Static` `Readonly` LENGTH

LENGTH: number = 32

Length of Secp256k1 ecdsa private key

Methods

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 Serializable.bcsToBytes
- Defined in src/bcs/serializer.ts:27

bcsToHex

bcsToHex(): Hex
Helper function to get a value's BCS-serialized bytes as a Hex instance.

Returns Hex
a Hex instance with the BCS-serialized bytes loaded into its underlying Uint8Array
Inherited from Serializable.bcsToHex
- Defined in src/bcs/serializer.ts:37

publicKey

publicKey(): Secp256k1PublicKey
Derive the Secp256k1PublicKey from this private key.

Returns Secp256k1PublicKey
Secp256k1PublicKey
Implementation of PrivateKey.publicKey
- Defined in src/core/crypto/secp256k1.ts:191

serialize

serialize(serializer): void
Parameters
- serializer: Serializer
Returns void
Overrides Serializable.serialize
- Defined in src/core/crypto/secp256k1.ts:218

sign

sign(message): Secp256k1Signature
Sign the given message with the private key.

Note: signatures are canonical, and non-malleable
Parameters
- message: HexInput
  a message as a string or Uint8Array
Returns Secp256k1Signature
Signature
Implementation of PrivateKey.sign
- Defined in src/core/crypto/secp256k1.ts:178

toString

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

Returns string
string representation of the private key
- Defined in src/core/crypto/secp256k1.ts:210

toUint8Array

toUint8Array(): Uint8Array
Get the private key in bytes (Uint8Array).

Returns Uint8Array
Implementation of PrivateKey.toUint8Array
- Defined in src/core/crypto/secp256k1.ts:201

`Static` deserialize

deserialize(deserializer): Secp256k1PrivateKey
Parameters
- deserializer: Deserializer
Returns Secp256k1PrivateKey
- Defined in src/core/crypto/secp256k1.ts:222

`Static` fromDerivationPath

fromDerivationPath(path, mnemonics): Secp256k1PrivateKey
Derives a private key from a mnemonic seed phrase.
Parameters
- path: string
  the BIP44 path
- mnemonics: string
  the mnemonic seed phrase
Returns Secp256k1PrivateKey
The generated key
- Defined in src/core/crypto/secp256k1.ts:140

`Static` `Private` fromDerivationPathInner

fromDerivationPathInner(path, seed): Secp256k1PrivateKey
A private inner function so we can separate from the main fromDerivationPath() method to add tests to verify we create the keys correctly.
Parameters
- path: string
  the BIP44 path
- seed: Uint8Array
  the seed phrase created by the mnemonics
Returns Secp256k1PrivateKey
The generated key
- Defined in src/core/crypto/secp256k1.ts:156

`Static` generate

generate(): Secp256k1PrivateKey
Generate a new random private key.

Returns Secp256k1PrivateKey
Secp256k1PrivateKey
- Defined in src/core/crypto/secp256k1.ts:127

`Static` isPrivateKey

isPrivateKey(privateKey): privateKey is Secp256k1PrivateKey
Parameters
- privateKey: PrivateKey
Returns privateKey is Secp256k1PrivateKey
Deprecated
use instanceof Secp256k1PrivateKey instead
- Defined in src/core/crypto/secp256k1.ts:232
