EncDec Library

Version: 1.00
Release Date: May 21st, 2007

Introduction

EncDec is a free Delphi unit to encode and decode string. It doesn't uses any sophisticated industry standard encryption method, it simply mimics base64 encoding with a configurable key. This unit is useful when you want to obscure a text and store it also as a string. I use this unit to store a string encoded in an INI file.

Installation

There is nothing to install. If you want to use this library, just copy EncDec.pas to your project and add EncDec to unit uses clause.
