Question

求教php AES/CBS/PKCS5Padding加密

Answer 1

要实现一个功能, 就是把字符串加密...
有一个java端的加密DEMO, 现在要转换成PHP实现..
但是PHP的得到的结果和JAVA得到的真的是完全不一样....
求大家帮帮忙,,, 看看哪里出问题了... THKS...

下面贴出JAVA端的DEMO:

byte[] encryptedData = cipher.doFinal(encryptString.getBytes("UTF8"));

String base64Str = new String(Base64.encodeBase64(encryptedData), "UTF8");

return URLEncoder.encode(base64Str, "utf-8");
