PowerShell Script Enable TLS 1.2

Introduction

As a programmer, it is crucial to ensure that the applications, systems or services that we build or use are secure, and that sensitive data is protected against unauthorized access. One of the ways to achieve this is by enabling Transport Layer Security (TLS) 1.2, which is a widely accepted encryption protocol used to establish secure connections over the internet.

In this article, we will explore how to enable TLS 1.2 in PowerShell, a task that can be easily done using a simple script.

Enabling TLS 1.2 in PowerShell

Before we dive into the PowerShell script, let's briefly review what TLS is and why it's important.

TLS is a cryptographic protocol that ensures secure communication between two computers over the internet. When two computers communicate, they exchange information that can contain sensitive data, such as login credentials, credit card information or personal details. TLS encrypts this data to ensure that only the intended recipient can read it, and prevents it from being intercepted by hackers or malicious actors.

To enable TLS 1.2 in PowerShell, follow these steps:

1. Open PowerShell as an Administrator.
2. Type the following command to create a registry key that will enable TLS 1.2:

New-Item 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319' -Force
New-ItemProperty -Path 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319' -Name 'SchUseStrongCrypto' -Value '1' -PropertyType 'DWord' -Force

3. Press Enter to execute the command.

This script creates a registry key that enables TLS 1.2 for .NET Framework 4.0.30319, which is the most widely used version of .NET Framework.

Conclusion

Enabling TLS 1.2 in PowerShell is a simple task that can greatly enhance the security of your systems and applications. By following the steps outlined above, you can easily create a registry key that enables TLS 1.2 for .NET Framework 4.0.30319. Remember to run PowerShell as an Administrator to ensure that the script runs correctly.
