سورس پروژه رمز نگاری ایمیل در ASP.NET

رمز نگاری ایمیل ، در این نمونه سورس که در محیط کنسول نوشته شده درمواقع عملیات های رمزنگاری در ارسال ایمیل را برسی کرده است ، این پروژه بیشتر در پروژه تحت وب میتواند کاربرد داشته باشد برای مثال یک فایل متنی که حاوی اطلاعات ایمیل است را به پروژه داده و میتوانید با الگوریتم های نوشته در نمونه سورس آن را به حالت Encoding میبرد.امید وارم استفاده کنید.سورس کامل نیز در ادامه براتون قرار دادم.
