I am trying to write the Java code to produce the similar result as the below java script produce for result1...
var dataToSign = "message";
var secret = "secret";
var orgId = "abcd";
var secureKey = "tZvFPMrVkgQ5m5jj";
var result1 = orgId+ CryptoJS.HmacSHA256(dataToSign, secret);
console.log( result1)
value of result1 is: abcd8b5f48702995c1598c573db1e21866a9b825d4a794d169d7060a03605796360b
Now i want to generate the same result using java code..
String orgId = "abcd";
String key="secret";
String dataToSign = "message";
Mac sha256_HMAC = Mac.getInstance("HmacSHA256");
SecretKeySpec secret_key = new SecretKeySpec(key.getBytes("UTF-8"), "HmacSHA256");
sha256_HMAC.init(secret_key);
String result2=orgId+java.util.Base64.getEncoder().encodeToString(sha256_HMAC.doFinal(dataToSign.getBytes("UTF-8")));
System.out.println(result2);
I am getting value of result2 is : abcd[B@39538f9e i19IcCmVwVmMVz2x4hhmqbgl1KeU0WnXBgoDYFeWNgs=
but I want result2 similar to result1;
Solution 1: You should this line
String result2=orgId+java.util.Base64.getEncoder().encodeToString(sha256_HMAC.doFinal(dataToSign.getBytes("UTF-8")));
To
String result2 = orgId + getHex(sha256_HMAC.doFinal(dataToSign.getBytes("UTF-8")));
Function getHex as below
static final String HEXES = "0123456789ABCDEF";
public static String getHex(byte[] raw) {
if (raw == null) {
return null;
}
final StringBuilder hex = new StringBuilder(2 * raw.length);
for (final byte b : raw) {
hex.append(HEXES.charAt((b & 0xF0) >> 4))
.append(HEXES.charAt((b & 0x0F)));
}
return hex.toString();
}
Solution 2: You should this line
var result1 = orgId+ CryptoJS.HmacSHA256(dataToSign, secret);
To
var result1 = orgId+ CryptoJS.HmacSHA256(dataToSign, secret);
var result2 = CryptoJS.enc.Base64.stringify(result1)
