正在获取HmacSHA1 Java哈希以匹配Powershell哈希

$key = 'test'
$bytes = [Text.Encoding]::UTF8.GetBytes($key)
WRITE-HOST "bytes: " $bytes
$hmacsha = new-object system.security.cryptography.HMACSHA1
$hmacsha.key = $bytes
$hash = $hmacsha.ComputeHash($bytes)
WRITE-HOST "hash: " $hash

结果是:

bytes:  116 101 115 116
hash:  12 148 81 92 21 229 9 91 138 135 165 11 160 223 59 243 142 208 95 230

在Java中:

String key = "test";
byte[] bytes = key.getBytes("UTF-8");
System.out.println("bytes: " + Arrays.toString(bytes));

MessageDigest md = MessageDigest.getInstance("SHA-1");
byte[] keyBytes = md.digest(bytes);
SecretKey sk = new SecretKeySpec(keyBytes, "HmacSHA1");
Mac mac = Mac.getInstance("HmacSHA1");
mac.init(sk);
byte[] hash = mac.doFinal(keyBytes);
System.out.println("hash 1: " + Arrays.toString(hash));

sk = new SecretKeySpec(bytes, "HmacSHA1");
mac = Mac.getInstance("HmacSHA1");
mac.init(sk);
hash = mac.doFinal(bytes);
System.out.println("hash 2: " + Arrays.toString(hash));

输出:

bytes: [116, 101, 115, 116]
hash 1: [-112, -37, 64, 65, -91, -97, 36, 60, -80, -110, 62, -105, -63, -69, -79, -18, 29, -95, 23, -116]
hash 2: [12, -108, 81, 92, 21, -27, 9, 91, -118, -121, -91, 11, -96, -33, 59, -13, -114, -48, 95, -26]

我似乎无法使哈希值与Powershell的输出相匹配。在这两个示例中,我都创建了一个键为“test”的hmacsha1实例,然后得到“test”的散列值,但是这两个实例都有一些微小的差异,导致它们给出不同的结果。
