Need to replicate similar to java or Python code
Java example
import javax.crypto.Mac;import javax.crypto.spec.SecretKeySpec;import java.nio.charset.StandardCharsets;import java.security.InvalidKeyException;import java.security.MessageDigest;import java.security.NoSuchAlgorithmException;import java.util.HexFormat;public class Main { public static void main(String[] args) throws NoSuchAlgorithmException, InvalidKeyException { final String secret = "It's a Secret to Everybody"; final String payload = "Hello World!"; final String givenSignature = "sha256=a4771c39fbe90f317c7824e83ddef3caae9cb3d976c214ace1f2937e133263c9"; final SecretKeySpec keySpec = new SecretKeySpec(secret.getBytes(StandardCharsets.UTF_8), "HmacSHA256"); final Mac mac = Mac.getInstance("HmacSHA256"); mac.init(keySpec); final byte[] digest = mac.doFinal(payload.getBytes(StandardCharsets.UTF_8)); final HexFormat hex = HexFormat.of(); final String calculatedSignature = "sha256=" + hex.formatHex(digest); if (!MessageDigest.isEqual(calculatedSignature.getBytes(), givenSignature.getBytes())) { System.out.println("Signatures do not match\nExpected signature:" + calculatedSignature + "\nActual: signature: " + givenSignature); } else { System.out.println("Signatures match"); } }}
Python example
import hashlibimport hmacsecret = "It's a Secret to Everybody"payload = "Hello World!"given_signature = "sha256=a4771c39fbe90f317c7824e83ddef3caae9cb3d976c214ace1f2937e133263c9"hash_object = hmac.new( secret.encode("utf-8"), msg=payload.encode("utf-8"), digestmod=hashlib.sha256,)calculated_signature = "sha256=" + hash_object.hexdigest()if not hmac.compare_digest(calculated_signature, given_signature): print( "Signatures do not match\nExpected signature:" f" {calculated_signature}\nActual: signature: {given_signature}" )else: print("Signatures match")
Apex:
I am struck on how to convert using crypto class - SecretKeySpec line.
any help will be much apricated?
