- 关于C# AES加密的PaddingMode的问题 20C
-
public static string AesEncrypt(string str, string key, string iv) { if (string.IsNullOrEmpty(str)) return null; Byte[] toEncryptArray = Encoding.UTF8.GetBytes(str); byte[] keyArr = Encoding.UTF8.GetBytes(key); byte[] ivArr = Encoding.UTF8.GetBytes(iv); System.Security.Cryptography.RijndaelManaged rm = new System.Security.Cryptography.RijndaelManaged(); /***************************这里有问题*****************************/ rm.Padding = System.Security.Cryptography.PaddingMode.None; /******************************************************************/ rm.Mode = System.Security.Cryptography.CipherMode.CFB; rm.BlockSize = 128; System.Security.Cryptography.ICryptoTransform cTransform = rm.CreateEncryptor(keyArr, ivArr); Byte[] resultArray = cTransform.TransformFinalBlock(toEncryptArray, 0, toEncryptArray.Length); return Convert.ToBase64String(resultArray, 0, resultArray.Length); }方法调用
String str = "appid=pm93c050eb69884a50&appsecret=b24ee0ef-73be-4a9a-a884-e0c0e27c×tamp=1489732369";
string aa = AesEncrypt(str, "dha@wjw$pvms9wwl", "8807599889957088");PaddingMode设置成PaddingMode.None 不填充时 总会报错
有人知道这个问题怎么解决吗

- yangbo50304 回复尛丶MaTure: 你确定java端是用了none还是没设置用的默认值？

- yangbo50304 设置成PaddingMode.PKCS7试试呢？

public static String aesEncrypt(String str, String key,String iv) throws Exception {
if (str == null || key == null)
return null;
SecretKeySpec keySpec=new SecretKeySpec(key.getBytes("utf-8"), "AES");
IvParameterSpec ivSpec = new IvParameterSpec(iv.getBytes(Charset.forName("UTF-8")));
Cipher cipher = Cipher.getInstance("AES/CFB/NOPADDING");
cipher.init(Cipher.ENCRYPT_MODE, keySpec, ivSpec);
byte[] bytes = cipher.doFinal(str.getBytes("utf-8"));
return new BASE64Encoder().encode(bytes);
}
