This is the Chilkat .NET Framework assembly for the .NET Framework (versions 2.0 to 4.8). It runs on Windows systems where the .NET Framework is installed. It is primarily designed for desktop applications, ASP.NET web applications, and legacy systems that target the .NET Framework.

About the Chilkat Library

The Chilkat .NET library is a comprehensive suite of software components that provide a wide range of functionality for use in .NET applications. These components are primarily focused on internet communications and cryptographic operations, making it easier for developers to handle tasks such as email processing, data encryption, file transfer protocols, and various internet-based services.

Here are some key features of the Chilkat .NET library:

1. Email and POP3/SMTP/IMAP Functionality

• Sending and receiving emails through SMTP, POP3, and IMAP protocols.
• Handling email attachments, multipart emails, and HTML emails.
• Support for secure email communication via SSL/TLS.
