How to create hashes (message digests) for strings.

Dim crypt As New ChilkatCrypt2

'  Any string argument automatically begins the 30-day trial.
Dim success As Long
success = crypt.UnlockComponent("30-day trial")
If (success <> 1) Then
    MsgBox "Crypt component unlock failed"

End If

'  Other possible EncodingMode settings are:
'  "quoted-printable", "base64", and "url"

Text1.Text = Text1.Text & "SHA1:" & vbCrLf

Text1.Text = Text1.Text & hash & vbCrLf

'  Hash using MD2

'  Hash using HAVAL
'  There are two additional properties relevant to HAVAL:
'  HavalRounds, and KeyLength.
'  HavalRounds can have values of 3, 4, or 5.
'  KeyLength can have values of 128, 160, 192, 224, or 256

Text1.Refresh
Text1.Text = Text1.Text & hash & vbCrLf
