Class PrivateKey

constructor

• new PrivateKey(priv, chainCode): ECDSA.PrivateKey

• Parameters

  • priv: KeyPair

    key pair priv (BN) pub (curve.base.BasePint) if applicable
  • chainCode: Uint8Array

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

  Returns ECDSA.PrivateKey

ReadonlykeyPair

bytes

• bytes(): Uint8Array

• Returns Uint8Array

  Uint8Array (if contains a private key)

  Throws

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

  Returns ECDSA.PrivateKey

  child PrivateKey of the current PrivateKey

derivePath

• derivePath(path): ECDSA.PrivateKey

• Parameters
