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。 –
