    encrypt.License( "your license key" ) 

    Dim rijndael As New XceedEncryptionLib.XceedRijndaelEncryptionMethodClass()
    Dim source As Object = "This is the data to encrypt"

    Try
      rijndael.SetSecretKeyFromPassPhrase( "This is a weak pass phrase", 128 )
      encrypt.EncryptionMethod = rijndael      

      Dim encryptedData As Object = encrypt.Encrypt( source, true ) 
    Catch except As System.Runtime.InteropServices.COMException
      MessageBox.Show( except.ToString() )
    End Try 

    VB.NET - Decryption Copy Code

    Dim encrypt As New XceedEncryptionLib.XceedEncryptionClass() 

    encrypt.License( "your license key" ) 

    Dim rijndael As New XceedEncryptionLib.XceedRijndaelEncryptionMethodClass() 

    Try
      rijndael.SetSecretKeyFromPassPhrase( "This is a weak pass phrase", 128 )
      encrypt.EncryptionMethod = rijndael

      Dim decryptedData As Object = encrypt.Decrypt( encryptedData, true ) 

      MessageBox.Show( System.Text.Encoding.Unicode.GetString( CType( decryptedData, Byte() ) ) )
    Catch except As System.Runtime.InteropServices.COMException
