btw, what's the length of the encrypted password that you get from
AspCrypt... that may ring some bells of mine...


So I guess it should be DES.

The result from AspCrypt's been somthing like
"aa0LEL4gR0chI"
where two first charactors are password salt.

And this is the code I adapt from one I found in Google

========================
Dim inputByteArray() As Byte = _
System.Text.Encoding.Default.GetBytes(Password)
Dim des As New DESCryptoServiceProvider
des.GenerateKey()
des.GenerateIV()

Dim ms As New MemoryStream
Dim cs As New CryptoStream( _
ms, des.CreateEncryptor(), CryptoStreamMode.Write)
cs.Write(inputByteArray, 0, inputByteArray.Length)
cs.FlushFinalBlock()

Dim ret As New System.Text.StringBuilder
For Each b As Byte In ms.ToArray()
ret.AppendFormat("{0:X2}", b)
Next
Return ret.ToString()
========================

I don't really understand the code above.
I don't even know how to put "salt" in it.

The result from this function looks like
"0E16710C4E90D4C2"
So I'm not sure do I go the right way.

Thanks,
