我写的.net 加密代码
public static string EncryptWithJava(string key, string str)
{
key = "998c5f7617ab6364";
str = "{abc123456abc}";
byte[] IV = Encoding.UTF8.GetBytes("12345678");
if (key.Length < 8 || string.IsNullOrEmpty(str))
{
throw new Exception("加密key小于8或者加密字符串为空！");
}
byte[] bKey = Encoding.UTF8.GetBytes(key.Substring(0, 8));
byte[] bIV = IV;
byte[] bStr = Encoding.UTF8.GetBytes(str);
try
{
DESCryptoServiceProvider desc = new DESCryptoServiceProvider();
desc.Padding = PaddingMode.PKCS7;//补位
desc.Mode = CipherMode.CBC;
using (MemoryStream mStream = new MemoryStream())
{
using (CryptoStream cStream = new CryptoStream(mStream, desc.CreateEncryptor(bKey, bIV), CryptoStreamMode.Write))
{
cStream.Write(bStr, 0, bStr.Length);
cStream.FlushFinalBlock();
StringBuilder ret = new StringBuilder();
byte[] res = mStream.ToArray();
return Convert.ToBase64String(res);
}
}
}
catch
{
return string.Empty;
}
}
java对{abc123456abc} ，秘钥：998c5f7617ab6364加密后：5pFKjYJqQ41T7IFbkzTbEQ==
.net 对{abc123456abc} ，秘钥：998c5f7617ab6364加密后: SqDbUMgK+GwKX93X0ps7jw==
请问一下各位兄弟，.net 是哪里写得不对吗？
