Chapter 1	Introduction & Quick Start	Contains a list of features, system requirements, and description of the expiration mechanism. Also contains a short code sample to get you started.
Chapter 2	Symmetric Encryption	Describes the Windows implementation of cryptography and cryptographic providers. Explains how to create, import and export symmetric keys, and encrypt/decrypt data with it.
Chapter 3	One-way Hash Functions	Explains what a one-way hash function is and its various applications, such as a secure password storage and file identification system.
Chapter 4	Certificates and Certificate Stores	Digital certificates are instrumental to asymmetric cryptography, i.e. encryption and signing based on public and private keys. This chapter explains how certificates are stored and organized, and sets the stage for the tour of AspEncrypt's various public-key cryptography functions.
Chapter 5	Secure Email	Describes the certificate-based secure email functionality of the AspEncrypt/AspEmail tandem.
Chapter 6	Digital Signatures	Explains how to generate and verify digital signatures.
Chapter 7	Issuing Certificates	Describes how to set up your own Certification Authority and issue certificates with the help of AspEncrypt.
Chapter 8	XEncrypt - Client-side ActiveX Control	AspEncrypt provides a client-side ActiveX sub-component, XEncrypt, which enables you to perform cryptographic operations on the user machine without jeopardizing the security of the user's private key.
Chapter 9	PKCS#7 Signatures and Envelopes	Explains how to generate detached digital signatures and envelopes (encrypted messages) in PKCS#7 format.
Chapter 10	Microsoft .NET and AspEncrypt Compatibility	Explains how to use the Microsoft .NET framework to properly decrypt data encrypted by AspEncrypt, and vice versa.
Appendix A	Publications & Reviews	Lists the books featuring AspEncrypt, online reviews, and relevant articles.
