Ben C # şifresini istiyorsunuz PHP şifreli bir dize var. Ben şifreleme yapmak için aşağıdaki öğretici kullandık, ama sorun şifresini yaşıyorum. Herkes bunu yapmak için nasıl bir örnek gönderebilir miyim?
http://www.sanity-free.org/131/triple_des_between_php_and_csharp.html
Umarım bu yardımcı olur:
class Program
{
static void Main(string[] args)
{
Console.WriteLine(Decrypt("47794945c0230c3d"));
}
static string Decrypt(string input)
{
TripleDES tripleDes = TripleDES.Create();
tripleDes.IV = Encoding.ASCII.GetBytes("password");
tripleDes.Key = Encoding.ASCII.GetBytes("passwordDR0wSS@P6660juht");
tripleDes.Mode = CipherMode.CBC;
tripleDes.Padding = PaddingMode.Zeros;
ICryptoTransform crypto = tripleDes.CreateDecryptor();
byte[] decodedInput = Decoder(input);
byte[] decryptedBytes = crypto.TransformFinalBlock(decodedInput, 0, decodedInput.Length);
return Encoding.ASCII.GetString(decryptedBytes);
}
static byte[] Decoder(string input)
{
byte[] bytes = new byte[input.Length/2];
int targetPosition = 0;
for( int sourcePosition=0; sourcePosition<input.Length; sourcePosition+=2 )
{
string hexCode = input.Substring(sourcePosition, 2);
bytes[targetPosition++] = Byte.Parse(hexCode, NumberStyles.AllowHexSpecifier);
}
return bytes;
}
}
Eğer TripleDESgereken bağlı, ama sadece php ve. Net arasındaki şifrelenmiş veri aktarmak gerek değilseniz, bu sizin için çalışacaktır. Bu VB ve aşağıdaki C # bulunuyor.
