Base64 String Encoding

Download: Chilkat .NET Assemblies

To access the encoding and charset conversion functionality without encryption, set the encryption algorithm to "none". This example shows how to base64-encode a string.

        ' This example uses the Chilkat .NET encryption library, which can be downloaded
        ' at http://www.chilkatsoft.com/downloads.asp

        ' Create an instance of the Chilkat encryption class.
        Dim crypt As New Chilkat.Crypt2()

        ' Any code begins the 30-day trial.
        crypt.UnlockComponent("30-day-trial")

        ' Do not use any encryption algorithm.
        crypt.CryptAlgorithm = "none"

        ' Tell the encryption object to return a base64 encoded string.
        crypt.EncodingMode = "base64"

        ' Base64 encode a string.
        TextBox2.Text = crypt.EncryptStringENC("This is a test")
        ' Base64 decode
        TextBox3.Text = crypt.DecryptStringENC(TextBox2.Text)
