Product Overview
The SocketTools 12 Library Edition includes native Windows libraries (DLLs) which provide an extensive collection of APIs for uploading and downloading files, accessing web-based services, sending and retrieving e-mail messages, executing commands on remote servers, interactive terminal sessions and much more.
SocketTools 12 introduces a Large Language Model (LLM) client library that provides a unified interface for integrating artificial intelligence capabilities into Windows applications. Developers can use the same programming model to connect to popular cloud-based AI services as well as locally hosted models, without having to implement provider-specific APIs or manage the complexities of individual service integrations.
The SocketTools libraries are native Windows DLLs, compatible with Visual Studio 2010 and later versions, including Visual Studio 2026. Both 32-bit and 64-bit libraries are included, along with native ARM64 support for C/C++, Visual Basic, Object Pascal, PowerBASIC and several other languages. SocketTools 12 has also introduced support for Windows on ARM with native ARM64 libraries.
SocketTools supports the major Internet protocols, including DNS, FTP, HTTP, ICMP, IMAP4, NNTP, POP3, SMTP, SSH and TELNET. General purpose TCP and UDP client and server support is also included, along with support for both IPv4 and IPv6 connections. A single interface provides both synchronous and asynchronous network connections.
Secure connections are supported using the Transport Layer Security (TLS) and Secure Shell (SSH) protocols with AES-256 bit encryption. Security features in the components can be enabled with just a few lines of code and do not require any experience with data encryption or cryptography.
The Library Edition provides a comprehensive API that is very similar in design to the standard Windows API. It uses the same calling conventions, and most functions use only integral data types, strings and simple structures. This makes it easy to use and the libraries are compatible with a wide variety of free and commercial development tools.
