如何使用充气城堡在Java中创建SHA512摘要字符串?

此单元测试失败:
public void testDigest() throws NoSuchAlgorithmException {
String hashExpected = "150a14ed5bea6cc731cf86c41566ac427a8db48ef1b9fd626664b3bfbb99071fa4c922f33dde38719b8c8354e2b7ab9d77e0e67fc12843920a712e73d558e197";
MessageDigest md = new MessageDigest();
String hashActual = new String(md.digest("hi"));
Assert.assertEquals(hashExpected, hashActual);
}
以下是我对MessageDigest类的实现:
import java.io.IOException;
import java.io.InputStream;
import java.security.NoSuchAlgorithmException;
import java.security.Security;
import org.bouncycastle.crypto.Digest;
import org.bouncycastle.crypto.digests.SHA512Digest;
import org.bouncycastle.crypto.io.DigestInputStream;
import org.bouncycastle.jce.provider.BouncyCastleProvider;
public class MessageDigest {
private Digest messageDigest;
public MessageDigest() throws NoSuchAlgorithmException {
Security.addProvider(new BouncyCastleProvider());
messageDigest = new SHA512Digest();
}
public byte[] digest(String message) {
byte[] retValue = new byte[messageDigest.getDigestSize()];
messageDigest.update(message.getBytes(), 0, message.length());
messageDigest.doFinal(retValue, 0);
return retValue;
}
}
测试失败,原因如下:
junit.framework.ComparisonFailure: expected:<150a14ed5bea6cc731cf86c41566ac427a8db48ef1b9fd626664b3bfbb99071fa4c922f33dde38719b8c8354e2b7ab9d77e0e67fc12843920a712e73d558e197> but was:<

我有一种感觉,当我将我的byte[]摘要转换为字符串时,我没有使用正确的编码方案。任何帮助将不胜感激。
