hi

i have a C# .net app with i decompiled. This app uses for login password
cryption:
http://www.obviex.com/samples/Sample.aspx?Source=EncryptionWithSaltCS&T itle=Encryption%20With%20Salt&Lang=C%23

C# Code
rijndaelKey = new Krypto.RijndaelEnhanced(passPhrase, initVector);
PlainPassword =
DiverseVariablen.rijndaelKey.Decrypt(Conversions.ToString(row["ProjectKennwort "])))

I have pass and iv.

How can i decrypt the passwords in php? I tryted allready several
variants of mcrypt_decrypt().

Didt somene have a idea?

Wha i dont understand is that the iv has 16 chars but it should be an
256b encryption with normaly depends a 32chars iv.

I also allready tryed a http://phpseclib.sourceforge.net/ for decryption
without any success.

Friendly regards and big thanks.
