I want to calculate the MD5 Hash of RichTextBox1.Text. I've added this line of code at the top so that I can use the MD5 encryption method: Imports System.Security.Cryptography. How do I go about actually calculating the hash?

1MD5 is no encryption. – Uwe Keim May 31 '15 at 16:53

I remember watching a video where they used `System.Security.Cryptography` to encrypt text into an md5 hash. – DomMC PvP May 31 '15 at 16:54

Note: The video was very bad quality. The only thing that stood out clearly was the class name and the namespace. – DomMC PvP May 31 '15 at 16:55

That's for console... Not VB.NET. – DomMC PvP May 31 '15 at 16:56

The process is described here.
The basic code from the link is:
Dim Bytes() As Byte
Dim sb As New StringBuilder()
Bytes = Encoding.Default.GetBytes(RichTextBox1.Text)
'Get md5 hash
Bytes = MD5.Create().ComputeHash(Bytes)
'Loop though the byte array and convert each byte to hex.
For x As Integer = 0 To Bytes.Length - 1
sb.Append(Bytes(x).ToString("x2"))
Next
'Return md5 hash.
Return sb.ToString()
