Function deriveHdPrivateNodeFromSeed

Parameters

• seed: Uint8Array

  the entropy from which to derive the HdPrivateNode

• __namedParameters: {
      assumeValidity?: AssumeValidity;
      crypto?: {
          sha512: {
              hash: ((input) => Uint8Array) & ((input) => Uint8Array);
          };
      };
      hmacSha512Key?: Uint8Array;
      throwErrors?: ThrowErrors;
  } = {}

  • Optional assumeValidity?: AssumeValidity

    If set, the derived private key will not be checked for validity, and will be assumed valid if true or invalid if false (this is useful for testing).

  • Optional crypto?: {
        sha512: {
            hash: ((input) => Uint8Array) & ((input) => Uint8Array);
        };
    }

    An optional object containing an implementation of sha512.

    • sha512: {
          hash: ((input) => Uint8Array) & ((input) => Uint8Array);
      }

      • hash: ((input) => Uint8Array) & ((input) => Uint8Array)

  • Optional hmacSha512Key?: Uint8Array

    The HMAC SHA-512 key to use (defaults to the HMAC SHA-512 key used by BIP32, utf8ToBin('Bitcoin seed').

  • Optional throwErrors?: ThrowErrors

    If true, invalid key derivations (probability less than 1 in 2^127) will throw an Error rather than returning an HdPrivateNodeInvalid (defaults to true).
