# Khác

```javascript
caver.klay.sha3(data[, callback])
```

Trả về hàm băm Keccak-256 (không phải là hàm băm SHA3-256 chuẩn hóa) của dữ liệu đã cho.

**Tham số**

| Tên      | type  | Mô tả                                                                                                           |
| -------- | ----- | --------------------------------------------------------------------------------------------------------------- |
| data     | Chuỗi | Dữ liệu cần chuyển đổi thành hàm băm SHA3.                                                                      |
| callback | Hàm   | (tùy chọn) Hàm callback tùy chọn, trả về một đối tượng lỗi làm tham số thứ nhất và kết quả làm tham số thứ hai. |

**Giá trị trả về**

`Promise` trả về `String` - Kết quả SHA3 của dữ liệu đã cho.

**Ví dụ**

```javascript
> caver.klay.sha3("0x11223344").then(console.log);
0x36712aa4d0dd2f64a9ae6ac09555133a157c74ddf7c079a70c33e8b4bf70dd73

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://archive-vn.docs.klaytn.foundation/content/dapp/sdk/caver-js/v1.4.1/api-references/caver.klay/misc.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
