c#代码是这样的(不能改变它，因为它是在客户端系统中)
namespace Common {
public static class EncryptionHelper
{
private const string cryptoKey = "password";
// The Initialization Vector for the DES encryption routine
private static readonly byte[] IV = new byte[8] { 240, 3, 45, 29, 0, 76, 173, 59 };
/// <summary>
/// Encrypts provided string parameter
/// </summary>
public static string Encrypt(string s)
{
string result = string.Empty;
byte[] buffer = Encoding.ASCII.GetBytes(s);
byte[] k = Encoding.ASCII.GetBytes(cryptoKey);
TripleDESCryptoServiceProvider des = new TripleDESCryptoServiceProvider();
MD5CryptoServiceProvider MD5 = new MD5CryptoServiceProvider();
des.Key = MD5.ComputeHash(ASCIIEncoding.ASCII.GetBytes(cryptoKey));
des.IV = IV;
result = Convert.ToBase64String(des.CreateEncryptor().TransformFinalBlock(buffer, 0, buffer.Length));
return result;
}
}
}
我发现客户端从这里开始上课:http://johnnycoder.com/blog/2008/07/03/c-encryption-decryption-helper-class/
我不是很熟悉c#，我需要解密字符串在PHP加密这段代码。
当我执行md5($key, true)我没有得到与"MD5.ComputeHash(ASCIIEncoding.ASCII.GetBytes(cryptoKey));"相同的结果，不知道为什么。
如何将"byte[] IV"转换为PHP字符串?
任何帮助都会很感激。谢谢你。
成功启动:
