I am writing a program in VB.NET that needs to encrypt some text using MD5 that will be going into a file. Are there any snippets of code that can do this or something that I can use?

You can try this site. There is an Active X DLL that works very well with VB6. Should work just as well with VB.NET

this site uses the built in md5 algorithms
http://www.flowgroup.fr/tech_md5_us.htm

note its written in C# but should be extremely easy to port because c# and vb.net both use the same functions, just different syntax

This should to the trick:

Public Function MD5(ByVal number As String) As String
'Create an encoding object to ensure the encoding standard for the source text
Dim ASCIIenc As New ASCIIEncoding
Dim strReturn
'Retrieve a byte array based on the source text
Dim ByteSourceText() As Byte = ASCIIenc.GetBytes(number)
'Instantiate an MD5 Provider object
Dim Md5Hash As New MD5CryptoServiceProvider
'Compute the hash value from the source
Dim ByteHash() As Byte = Md5Hash.ComputeHash(ByteSourceText)
'Cycle through the hash and convert to string
For Each b As Byte In ByteHash
'Convert byte(s) to string
strReturn &= b.ToString("x2")
Next
'Return the result
Return strReturn
End Function

Just call MD5("12345") from within your code.

what does die x2 mean?

thanx in advance
