Hi!

I need to compare 2 sets of odd data.  I figure a CRC32 check should do the trick.  How?

I've looked at a lot of 3rd party components and I just need something simple like:

MyCRC32 = GetCRC32(Mydata as String)

All I seem to find are mammoth applications with a ton of extra crap.  I don't want to browse for files, set up timers (???) etc.  Just a simple CRC32/MD5/Whatever routine to generate a checksum for a string value.

The simplest solution gets the points.

 Public Function ComputeMD5Hash(ByVal inputString As String) As String

    Dim md5Provider As New System.Security.Cryptography.MD5CryptoServiceProvider

    Dim bytesInput() As Byte = System.Text.UTF8Encoding.UTF8.GetBytes(inputString)

    Dim bytesHash() As Byte = md5Provider.ComputeHash(bytesInput)

    Return System.Text.UTF8Encoding.UTF8.GetString(bytesHash)

  End Function 'ComputeMD5Hash'
