Hello,
I've never been dealing with the security before. Could you please help me
to write a code to generate an MD5 data from a string? I've been using this
example from MSDN:
Function MD5hash(data() As Byte) As Byte()
' This is one implementation of the abstract class MD5.
Dim md5 As New MD5CryptoServiceProvider()
Dim result As Byte() = md5.ComputeHash(data)
Return result
End Function
but perhaps made a mistake converting string to byte and couldn't fix it.
My string looks like this:
sCRC = "avp:" & dblSum.ToString & ":" & CLng(Format(Now, "yyyyMMddHHmmss"))
_
& ":pa0107THOP:shp_UserID=" & sUser _
& ":shp_Price=" & dblPrice.ToString & ":shp_PaymentNo=" _
& CLng(Format(Now, "yyyyMMddHHmmss")) & ":shp_Term=" _
& sTerm & ":shp_Email=" & sEmail
I will be passing this parameter as a querystring.
I would really appreciate your help.
Thank you,

And the exact problem is (how do you convert) ?
I would suggest http://msdn.microsoft.com/library/de...simplified.asp

Thank you, Patrice.
I'll try this, if it doesn't work I'll post my conversion here.

The absolute simplest way is to use:
string md5= System.Web.Security.FormsAuthentication.HashPasswo rdForStoringInConfigFile( str,"MD5");
where str is your string you want to computer the hash from and the last argument can
be "MD5" or "SHA1"
For more info look this up in the docs.
