Is Crypto.generateMac method work exactly the same as Mac and SecretKeySpec java classes
I need to create a signature in order to send a request to CyberSource. I have the following Java code, that works perfectly:
String signatureString = "Test";
final Mac sha256HMAC = Mac.getInstance("HmacSHA256");
final SecretKeySpec secretKey = new SecretKeySpec(
Base64.getDecoder().decode("LZjfTQi8uxEn5VFI3S4Ml+8UY4y3b2F0aP8c8WuiQtY="), "HmacSHA256");
sha256HMAC.init(secretKey);
sha256HMAC.update(signatureString.toString().getBytes(StandardCharsets.UTF_8));
final byte hashBytes = sha256HMAC.doFinal();
final String signatureB64 = Base64.getEncoder().encodeToString(hashBytes);
System.out.println(signatureB64.toString()); //nbXkkkM3GuPp8YEIb7JnAj4IrDy0YC7t3Pl/cJxStW0=
I tried to make the same on Apex, but it shows me different result:
String signatureString = 'Test';
System.debug(generateHmacSHA256Signature(signatureString, 'LZjfTQi8uxEn5VFI3S4Ml+8UY4y3b2F0aP8c8WuiQtY=')); //5zJnHFYz6HklMZ8vR4rf7UJfjrumiexZeYDgsuErrk=
public static String generateHmacSHA256Signature(String input, String secretKey) {
String algorithmName = 'HmacSHA256';
Blob mac = Crypto.generateMac(algorithmName, Blob.valueOf(input), Blob.valueOf(Secretkey));
String macUrl = EncodingUtil.base64Encode(mac);
return macUrl;
}
So Java returns nbXkkkM3GuPp8YEIb7JnAj4IrDy0YC7t3Pl/cJxStW0= and Apex 5zJnHFYz6HklMZ8vR4rf7UJfjrumiexZeYDgsuErrk= results are different.
How can I get the same result, as in Java? Any help very appriciated.

Your Apex code just misses the base64 decoding step on your secret key. If you change the call to generateMac() to this:
Blob mac = Crypto.generateMac(algorithmName, Blob.valueOf(input), EncodingUtil.base64Decode(Secretkey));
You'll get back

I wasted almost all day to try different combinations ofEncodingUtil.base64DecodeandBlob.valueOf, but on more complicated input... What's a fresh view mean!
