Overview

Using client-proven methods, and over 15 years of programming experience, expert author Davis Chapman empowers developers to create powerful, secure applications. Developing Secure Applications with Visual Basic first provides you with an understanding of encryption, and then guides you through adding security features to your own applications using the Microsoft CryptoAPI, and the new security features of Windows 2000. Developers who have been confused by the high-end, academic style of other encryption books and cryptography theory will delight with Chapman's understandable style and hands-on methods. This book covers security topics developers want and need to know including File Encryption, Encrypted Communications, Working with Certificates, Digital Signatures, SChannel Communications (SSL), Secure E-Mail, and much more.
