Calculate HMAC-SHA1 Signature using JavaScript
提问by anchor
I am writing a JavaScript Client Application that needs to communicate with Server. I tried to implement the API, but i stuck on one method and I need help.
我正在编写一个需要与服务器通信的 JavaScript 客户端应用程序。我试图实现 API，但我坚持使用一种方法，我需要帮助。
Infect i don't know how to translate this from Java to JavaScript (I don't know where to find analog libraries written in javascript that are used in this method):
感染我不知道如何将其从 Java 转换为 JavaScript（我不知道在哪里可以找到在此方法中使用的用 javascript 编写的模拟库）：
import java.security.SignatureException;
import javax.crypto.Mac;
import javax.crypto.spec.SecretKeySpec;
/**
* This class defines common routines for generating
* authentication signatures for AWS requests.
*/
public class Signature {
private static final String HMAC_SHA1_ALGORITHM = "HmacSHA1";
/**
* Computes RFC 2104-compliant HMAC signature.
* * @param data
* The data to be signed.
* @param key
* The signing key.
* @return
* The Base64-encoded RFC 2104-compliant HMAC signature.
* @throws
* java.security.SignatureException when signature generation fails
*/
public static String calculateRFC2104HMAC(String data, String key)
throws java.security.SignatureException
{
String result;
try {
// get an hmac_sha1 key from the raw key bytes
SecretKeySpec signingKey = new SecretKeySpec(key.getBytes(), HMAC_SHA1_ALGORITHM);
// get an hmac_sha1 Mac instance and initialize with the signing key
Mac mac = Mac.getInstance(HMAC_SHA1_ALGORITHM);
mac.init(signingKey);
// compute the hmac on input data bytes
byte[] rawHmac = mac.doFinal(data.getBytes());
// base64-encode the hmac
result = Encoding.EncodeBase64(rawHmac);
} catch (Exception e) {
throw new SignatureException("Failed to generate HMAC : " + e.getMessage());
}
return result;
}
}
This method is from AWS Documentations: Java Sample Code for Calculating HMAC-SHA1 Signatures
此方法来自 AWS 文档： 用于计算 HMAC-SHA1 签名的 Java 示例代码
I am asking if someone can give me some references (websites) where I can find solution or analog libraries, written in javascript.
我在问是否有人可以给我一些参考资料（网站），在那里我可以找到用 javascript 编写的解决方案或模拟库。
I searched AWS Documentation and SDK for JavaScript and I couldn't find translation in JS.
我搜索了适用于 JavaScript 的 AWS 文档和开发工具包，但在 JS 中找不到翻译。
Thanks very much in advance.
首先十分感谢。
