從AES加密字符串中刪除\ r和\ n

我使用AES加密字符串，但加密字符串最後包含\n和\r。從AES加密字符串中刪除 r和 n

public class AESImpl { 

    private static String decryptedString; 

    private static String encryptedString; 

    public static void main(String[] args) throws NoSuchAlgorithmException, IOException, ClassNotFoundException { 

    String strToEncrypt = "This text has to be encrypted"; 
    SecretKey secretKey = generateSecretKey(); 
    String encryptStr = encrypt(strToEncrypt, secretKey); 
    System.out.println("Encrypted String : " + encryptStr + "It should not come in new line"); 
    String decryptStr = decrypt(encryptStr, secretKey); 
    System.out.println("Decrypted String : " + decryptStr); 
    } 

    private static SecretKey generateSecretKey() throws NoSuchAlgorithmException, IOException { 
    KeyGenerator kg = KeyGenerator.getInstance("AES"); 
    kg.init(128); 
    SecretKey sk = kg.generateKey(); 
    String secretKey = String.valueOf(Hex.encodeHex(sk.getEncoded())); 
    System.out.println("Secret key is " + secretKey); 
    return sk; 
    } 

    public static String encrypt(String strToEncrypt, SecretKey secretKey) { 
    try { 
     Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5PADDING"); 
     cipher.init(Cipher.ENCRYPT_MODE, secretKey); 
     encryptedString = new String(Base64.encodeBase64String(cipher.doFinal(strToEncrypt.getBytes()))); 
    } catch (Exception e) { 
     System.out.println("Error while encrypting: " + e.toString()); 
    } 

    return encryptedString; 
    } 

    public static String decrypt(String strToDecrypt, SecretKey secretKey) { 
    try { 
     Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5PADDING"); 
     cipher.init(Cipher.DECRYPT_MODE, secretKey); 
     decryptedString = new String(cipher.doFinal(Base64.decodeBase64(strToDecrypt))); 
    } catch (Exception e) { 
     System.out.println("Error while decrypting: " + e.toString()); 
    } 

    return decryptedString; 
    } 
}

輸出

Secret key is 2df36561b09370637d35b4a310617e60 
Encrypted String : TUDUORnWtsZFJAhBw1fYMF9CFExb/tSsLeDx++cpupI= 
It should not come in new line 
Decrypted String : This text has to be encrypted

實際上，加密的字符串是TUDUORnWtsZFJAhBw1fYMF9CFExb/tSsLeDx++cpupI=/r/n。我是否需要從加密字符串中明確地替換\r和\n或者我在上面的代碼中做了一些錯誤？

Base64字符串中的空白被忽略。沒有任何錯誤。雖然可能有一個Base64編碼器選項來防止添加字符。 –
