如何将 Java AES - CBC 与 PKCS5 填充更改为 PHP

Question

我正在尝试将 JAVA 加密更改为 PHP 并产生完全相同的结果。我有以下准则。AES - CBC 与 PKCS5 填充对称加密方案：加密密钥大小为 128 位大小。初始化向量（IV）：-新的随机 IV 将在每个请求中使用。-在单个 Web 服务请求中，在加密所有加密字段时将使用相同的 IV。-此 IV 将在名称为“IV”的 SOAP Header 中传递。IV 值将采用 Base64 编码。我试过这个https://gist.github.com/thomasdarimont/fae409eaae2abcf83bd6633b961e7f00public class AESEncryptionUtil {public static final String CLASS_NAME = AESEncryptionUtil.class.getName(); private static final int KEY_SIZE = 16;private static final String ALGORITHM_AES = "AES";public final static String ALGORITHM_AES_CBC = "AES/CBC/PKCS5Padding";private static Key generateKey(String keyValue) throws Exception { Key key = null ;if (keyValue!=null && keyValue.length()==KEY_SIZE){byte[] byteKey = keyValue.substring(0, KEY_SIZE).getBytes("UTF-8");  key = new SecretKeySpec(byteKey, ALGORITHM_AES);}else{System.out.println("Not generating the Key!! "+keyValue); }return key; }/*** Return Base64 Encoded value of IV ** @param keyValue * @return* @throws Exception */public static String generateIV(String keyValue) throws Exception { String iv = null ;Key key = generateKey(keyValue); if (key!=null){Cipher cipher = Cipher.getInstance(ALGORITHM_AES_CBC); cipher.init(Cipher.ENCRYPT_MODE, key); AlgorithmParameters params =     cipher.getParameters();iv = new BASE64Encoder().encode(params.getParameterSpec(IvParameterSpec.class).getIV());  }else{System.out.println("No IV generated ...");}return iv; }/*** Method to perform encryption of given data with AES Algorithm / Key and IV. * @param encKey -*Encryption Key value * @param plainVal -*Value to be encrypted * @return - encrypted String Value * @throws   Exception*/

我设法得到一些工作

<?php

$string = "online1234";

$key = "haskingvista127$";

$iv  = base64_encode(openssl_random_pseudo_bytes(openssl_cipher_iv_length('aes-128-cbc')));

$encodedEncryptedData = base64_encode(openssl_encrypt($string, "AES-128-CBC", $key, OPENSSL_RAW_DATA, base64_decode($iv)));

$decryptedData = openssl_decrypt(base64_decode($encodedEncryptedData), "AES-128-CBC", $key, OPENSSL_RAW_DATA, base64_decode($iv));

?>

希望这可以帮助别人
