Function deriveHdPrivateNodeIdentifier

Parameters

• hdPrivateNode: HdPrivateNodeValid

  the HdPrivateNode from which to derive the public identifier (not require to be valid)

• crypto: {
      ripemd160: {
          hash: ((input: Uint8Array) => Uint8Array);
      };
      secp256k1: {
          derivePublicKeyCompressed: ((privateKey: Uint8Array) => string | Uint8Array);
      };
      sha256: {
          hash: ((input: Uint8Array) => Uint8Array);
      };
  } = ...

  an optional object containing implementations implementations of sha256, ripemd160, and secp256k1 compressed public key derivation to use

  • ripemd160: {
        hash: ((input: Uint8Array) => Uint8Array);
    }

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

      • • (input: Uint8Array): Uint8Array

        • Returns the ripemd160 hash of the provided input.

          To incrementally construct a ripemd160 hash (e.g. for streaming), use init, update, and final.

          Parameters

          • input: Uint8Array

            a Uint8Array to be hashed using ripemd160

          Returns Uint8Array

  • secp256k1: {
        derivePublicKeyCompressed: ((privateKey: Uint8Array) => string | Uint8Array);
    }

    • derivePublicKeyCompressed: ((privateKey: Uint8Array) => string | Uint8Array)

      • • (privateKey: Uint8Array): string | Uint8Array

        • Derive a compressed public key from a valid secp256k1 private key.

          Returns an error message if the provided private key is too large (see validatePrivateKey).

          Parameters

          • privateKey: Uint8Array

            a valid secp256k1, 32-byte private key

          Returns string | Uint8Array

  • sha256: {
        hash: ((input: Uint8Array) => Uint8Array);
    }

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

      • • (input: Uint8Array): Uint8Array

        • Returns the sha256 hash of the provided input.

          To incrementally construct a sha256 hash (e.g. for streaming), use init, update, and final.

          Parameters

          • input: Uint8Array

            a Uint8Array to be hashed using sha256

          Returns Uint8Array
