Welcome to IPWorks SSL, a secure suite of components where SSL/TLS is the only option. IPWorks SSL is a subset of our flagship IPWorks toolkit intended for environments where security must be enforced. IPWorks SSL components are drop-in replacements for their IPWorks counterpart, and will throw an error if plaintext communication is attempted. The enterprise-class components facilitate tasks, such as ensuring security, sending e-mails, transferring files, managing networks, browsing the web, consuming web services, and more.

Included Libraries

The .NET Edition includes several libraries (.dll files) which are supported in different environments. The following libraries are present in the lib directory after installation:

  • lib\nsoftware.IPWorksSSL.dll is designed for use in .NET Framework 4.0 and up, .NET Core 3.0 and up, and .NET 5 and up. This is the default library which maintains a familiar API in line with previous versions of the product.

    Support for asynchronous programming patterns (async/await) is exposed in a separate nsoftware.async.IPWorksSSL namespace. See the Async Functionality page for details.

  • lib\net6.0\nsoftware.IPWorksSSL.dll is designed for use in .NET 6 and up. The .NET 6 library provides cross-platform support while maintaining the same API as the default library in lib.

  • lib\netstandard2.0\nsoftware.IPWorksSSL.dll is designed for use in .NET Standard 2.0 and up. The .NET Standard library provides cross-platform support for legacy projects.

  • lib\net20\nsoftware.IPWorksSSL.dll is designed for use in .NET Framework 2.0 and up. This library targets .NET Framework 2.0 and is maintained for legacy projects.
