Chilkat Socket ActiveX 2.3

Chilkat Socket ActiveX is a COM/ActiveX component for Windows that streamlines TCP/IP and secure socket programming. Built by Chilkat Software Inc, it enables developers to create custom network clients and servers, add TLS/SSL encryption, and exchange text or binary data from any language that supports ActiveX (for example, VB6, VBA, classic ASP, C/C++, Delphi, and PowerBuilder). Its straightforward API handles connections, timeouts, and data transfer with minimal code.

Key features:

• Client and server TCP sockets with optional TLS/SSL encryption
• IPv4 and IPv6 support
• Certificate-based security, including server certificate validation and client certificate authentication (mutual TLS)
• HTTP and SOCKS proxy support
• Synchronous/blocking operations and asynchronous execution via background tasks with event/callback support
• Flexible reading and writing of strings or binary data, including line-based and length-prefixed operations, with common text encodings (such as UTF-8 and ANSI)
• Configurable connection and read/write timeouts, plus TCP keep-alives
• Thread-safe design suitable for multi-threaded applications
• Well-documented API with numerous examples and a redistributable runtime

Typical use cases:

• Building secure clients for proprietary or legacy protocols
• Implementing lightweight TCP servers and services
• Connecting to devices and gateways over encrypted channels
• Accessing services through corporate proxies

Compatibility:

• Windows (32-bit and 64-bit)
• Usable from any COM/ActiveX-aware development environment
