Class PrivateKey

constructor

• new PrivateKey(
      priv: { curve: CurveName; secretKey: BN },
      chainCode: Uint8Array,
  ): ECDSA.PrivateKey

  Parameters

  • priv: { curve: CurveName; secretKey: BN }

    { secretKey: BN, curve: 'p256' | 'secp256k1' }

  • chainCode: Uint8Array

    slice 32->n HMAC hash key and seedkey (first instance curve default seedKey. after hmac value slice 32->n)

  Returns ECDSA.PrivateKey

bytes

• bytes(): Uint8Array

  Returns Uint8Array

  Uint8Array (if contains a private key)

  Throws

derive

• derive(index: number): ECDSA.PrivateKey

  Parameters

  • index: number

    derivation path item pre-hardened if applicable ie: 44' -> 2^31 + 44

  Returns ECDSA.PrivateKey

  child PrivateKey of the current PrivateKey

derivePath

• derivePath(path: Iterable<number>): ECDSA.PrivateKey

  Parameters
