我正在嘗試將 JAVA 加密更改為 PHP 并產生完全相同的結果。我有以下準則。AES - CBC 與 PKCS5 填充對稱加密方案：加密密鑰大小為 128 位大小。初始化向量（IV）：-新的隨機 IV 將在每個請求中使用。-在單個 Web 服務請求中，在加密所有加密字段時將使用相同的 IV。-此 IV 將在名稱為“IV”的 SOAP Header 中傳遞。IV 值將采用 Base64 編碼。我試過這個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!!
