我正在嘗試將用于AES加密的Java代碼復(fù)制到Golang中。但是，我在golang中沒有得到相同的輸出我嘗試了以下代碼：Java 代碼：package EncryptionTest;import java.security.Key;import java.util.Base64;import javax.crypto.Cipher;import javax.crypto.spec.SecretKeySpec;public class EncryptionDecryptionAES { static Cipher cipher; public static void main(String[] args) throws Exception { Key secretKey; secretKey = (Key)new SecretKeySpec("0123456789012345".getBytes(), "AES"); cipher = Cipher.getInstance("AES"); String plainText = "AES Symmetric Encryption Decryption"; System.out.println("Plain Text Before Encryption: " + plainText); String encryptedText = encrypt(plainText, secretKey); System.out.println("Encrypted Text After Encryption: " + encryptedText); String decryptedText = decrypt(encryptedText, secretKey); System.out.println("Decrypted Text After Decryption: " + decryptedText); } public static String encrypt(String plainText, Key secretKey) throws Exception { byte[] plainTextByte = plainText.getBytes(); cipher.init(Cipher.ENCRYPT_MODE, secretKey); byte[] encryptedByte = cipher.doFinal(plainTextByte); Base64.Encoder encoder = Base64.getEncoder(); String encryptedText = encoder.encodeToString(encryptedByte); return encryptedText; } public static String decrypt(String encryptedText, Key secretKey) throws Exception { Base64.Decoder decoder = Base64.getDecoder(); byte[] encryptedTextByte = decoder.decode(encryptedText); cipher.init(Cipher.DECRYPT_MODE, secretKey); byte[] decryptedByte = cipher.doFinal(encryptedTextByte); String decryptedText = new String(decryptedByte); return decryptedText; }}Java 代碼輸出：加密前純文本：AES 對(duì)稱加密 解密 加密后加密文本：vSmrgH3qU+qEq+3ui0YvwCa6PDBcMyhgOlbh3+zzM+cON6feLk2u1iPW7lITD3vn 解密后的文本：AES 對(duì)稱加密解密戈朗代碼：package mainimport ( "crypto/aes" "crypto/cipher" "encoding/base64" "fmt")

在go代碼中，您在GCM模式下使用AES，其中12個(gè)字節(jié)為零作為IV，但在java代碼中，您使用的是AES的默認(rèn)模式，這在不同的java版本中是不一樣的。
通過使用GCM模式（在BouncyCastle中提供）并設(shè)置相同的IV（12字節(jié)零），我得到了相同的輸出：
package EncryptionTest;
import org.bouncycastle.jce.provider.BouncyCastleProvider;
import java.security.Key;
import java.security.Security;
import java.util.Base64;
import javax.crypto.Cipher;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;
public class EncryptionDecryptionAES {
static Cipher cipher;
public static void main(String[] args) throws Exception {
Security.addProvider(new BouncyCastleProvider());
Key secretKey;
secretKey = (Key)new SecretKeySpec("0123456789012345".getBytes(), "AES");
cipher = Cipher.getInstance("AES/GCM/NoPadding", "BC");
String plainText = "AES Symmetric Encryption Decryption";
System.out.println("Plain Text Before Encryption: " + plainText);
String encryptedText = encrypt(plainText, secretKey);
System.out.println("Encrypted Text After Encryption: " + encryptedText);
String decryptedText = decrypt(encryptedText, secretKey);
System.out.println("Decrypted Text After Decryption: " + decryptedText);
}
public static String encrypt(String plainText, Key secretKey) throws Exception {
byte[] plainTextByte = plainText.getBytes();
byte[] iv = new byte[12];
IvParameterSpec ivParameterSpec = new IvParameterSpec(iv);
cipher.init(Cipher.ENCRYPT_MODE, secretKey, ivParameterSpec);
byte[] encryptedByte = cipher.doFinal(plainTextByte);
Base64.Encoder encoder = Base64.getEncoder();
String encryptedText = encoder.encodeToString(encryptedByte);
return encryptedText;
}
public static String decrypt(String encryptedText, Key secretKey) throws Exception {
Base64.Decoder decoder = Base64.getDecoder();
byte[] encryptedTextByte = decoder.decode(encryptedText);
byte[] iv = new byte[12];
IvParameterSpec ivParameterSpec = new IvParameterSpec(iv);
cipher.init(Cipher.DECRYPT_MODE, secretKey, ivParameterSpec);
byte[] decryptedByte = cipher.doFinal(encryptedTextByte);
String decryptedText = new String(decryptedByte);
return decryptedText;
}
}
輸出：
Plain Text Before Encryption: AES Symmetric Encryption Decryption
Encrypted Text After Encryption: 7UMh49c5Wqb2BzlttKBEnq5g4fxMK9oJs1EUDIgWzVwlY28k+qd/oFG9SJckBsaX6DHp
Decrypted Text After Decryption: AES Symmetric Encryption Decryption
