問題：
我已在Go 中使用AES 成功加密文字。然而，我在用 Java 解密加密文字時面臨挑戰。您能否提供有關了解 Java 解密流程和工作 Java 解碼器的協助？
答案：
Java 解碼器：
<code class="java">import java.nio.charset.StandardCharsets;
import java.security.InvalidAlgorithmParameterException;
import java.security.InvalidKeyException;
import java.security.NoSuchAlgorithmException;
import java.util.Arrays;
import java.util.Base64;
import javax.crypto.BadPaddingException;
import javax.crypto.Cipher;
import javax.crypto.IllegalBlockSizeException;
import javax.crypto.IvParameterSpec;
import javax.crypto.NoSuchPaddingException;
import javax.crypto.SecretKeySpec;
public class AesDecrypter {
public static String decode(String base64Text, byte[] key) throws NoSuchPaddingException, NoSuchAlgorithmException,
InvalidAlgorithmParameterException, InvalidKeyException, BadPaddingException, IllegalBlockSizeException {
byte[] inputArr = Base64.getUrlDecoder().decode(base64Text);
SecretKeySpec skSpec = new SecretKeySpec(key, "AES");
Cipher cipher = Cipher.getInstance("AES/CFB/NoPadding");
int blockSize = cipher.getBlockSize();
IvParameterSpec iv = new IvParameterSpec(Arrays.copyOf(inputArr, blockSize));
byte[] dataToDecrypt = Arrays.copyOfRange(inputArr, blockSize, inputArr.length);
cipher.init(Cipher.DECRYPT_MODE, skSpec, iv);
byte[] result = cipher.doFinal(dataToDecrypt);
return new String(result, StandardCharsets.UTF_8);
}
}</code>Scala 解碼器： 🎜>
<code class="scala">import java.nio.charset.StandardCharsets
import javax.crypto._
import java.security.spec.IvParameterSpec
import java.security.spec.SecretKeySpec
import java.util.Base64
object AesDecrypter {
def decode(input:String, key:String): String = {
val cipher = Cipher.getInstance("AES/CFB/NoPadding")
val blockSize = cipher.getBlockSize()
val keyBytes = key.getBytes()
val inputArr = Base64.getUrlDecoder().decode(input)
val skSpec = new SecretKeySpec(keyBytes, "AES")
val iv = new IvParameterSpec(inputArr.slice(0, blockSize).toArray)
val dataToDecrypt = inputArr.slice(blockSize, inputArr.size)
cipher.init(Cipher.DECRYPT_MODE, skSpec, iv)
new String(cipher.doFinal(dataToDecrypt.toArray))
}
}</code>演示：
出於演示目的，讓我們對字串「test text 123」進行編碼用Go編寫的加密函數並用Java（或Scala ）編寫的解密函數對其進行解碼：以上是在 Go 中加密時如何在 Java 中解密 AES 加密文字？的詳細內容。更多資訊請關注PHP中文網其他相關文章！
