Introducing GlassWire Lite!

GlassWire Firewall Lite with less resources

Since GlassWire was introduced in 2014 over 20 million people have used our software to help protect their devices from privacy violating apps, bandwidth hogs, and malware.

However, for some people who need to use very minimal hardware resources, GlassWire’s resource usage requirements can be just a little too much.

For example we have one customer who runs a server at a remote location with very limited connectivity and limited resources. It’s critical that they use GlassWire to secure their server and keep their bandwidth in check, but they are also extremely limited by the unique server hardware they use.

We’ve listened carefully to the feedback from that customer and others who have unique hardware resource usage requirements and we’ve designed a special version of GlassWire just for them.

Today we’re excited to introduce GlassWire Lite! This optional new version of GlassWire uses less than 1/3 the memory that our normal GlassWire software uses and writes 1/20th of the disk write operations. And just like our original GlassWire version its CPU usage should usually be almost zero.

To make this super light version of GlassWire we made it collect very minimal host data. If you’re using GlassWire Lite you’ll find you’ll only see hosts on the Firewall tab, and in “New” and “Ask to Connect” notifications.

If tracking hosts is important to you then you’ll probably want to stick with our powerful original GlassWire version. But if you don’t need to track hosts we recommend that you give GlassWire Lite a try.

If you’re a Basic, Pro, or Elite user you can use your license on GlassWire Lite and it works exactly the same.

Please note if you switch to GlassWire Lite from our original GlassWire version your history and settings will be completely reset because GlassWire Live uses a different database structure. Our installer window warns about this.

However, when you install GlassWire Lite over GlassWire, your original GlassWire history will be backed up and moved inside the GlassWire folder. If you find GlassWire Lite is not for you then you should be able to install GlassWire again over itself, and your original GlassWire history should return with no issues.

Please note if you’re concerned about losing your GlassWire history you can back up your database before trying GlassWire Lite.

To try GlassWire Lite visit our download page, then look for the logo at the bottom left of the page and download it.

We hope you enjoy this new version of GlassWire and we appreciate your feedback.

3 simple ways to check a file’s hash with Windows

Why would someone want to know the hash of a file on Windows?

Software developers sometimes list the hash of a file when distributing it over the Internet to help others verify the file’s integrity.

Please see this SHA256 hash example for our GlassWire installer version 2.2.201.

The purpose of publishing the hash is to help you verify that the file you are downloading is the actual file the developer is distributing.

If the file is manipulated some way then the hash will change. For example, perhaps the file is actually malware or perhaps some other change has been made to the file to make it malicious in some way. Or maybe it’s the completely wrong file that was mistakenly uploaded to the wrong place.

How can I check a file’s hash on Windows?

One super quick and easy way to check a file is to upload the file to VirusTotal.com. VirusTotal is a free file analysis service created for the information security community. You can upload the file there and it will automatically show you the hash of the file. Then on top of this it will also show how the file is analyzed by many different antivirus engines. Please note that VirusTotal is not an antivirus, and some engines may incorrectly analyze a file as malware. This false analysis is called a false positive.

Please also note that you’ll be uploading this file to a third party server so you should not upload any files that should be kept private.

A second more private way to check a file’s hash is to open the Windows command prompt and use the certutil command for Windows.

An example of this simple command is below:

certutil -hashfile c:\Users\YourUserName\Desktop\wire.exe SHA256

This Windows command example would return the SHA256 hash of the file located at the specified path. You should update the command to show the correct path, user name, and file name for your file integrity check.

You can also use other values after SHA, such as 1 or 256, to produce the corresponding hash. With GlassWire’s example above we have chosen to use a SHA256 hash for our file.

A third easy way to find the hash of a file is to use the Windows 10 Power Shell. First open the Windows Powershell (click “Start” then type “Powershell” then click it), then use the command below checking the file “wire.exe” as an example. Of course YourUserName should be your user name, and you should use the correct path to the file you want to check.

Get-FileHash -Path c:\Users\YourUserName\Desktop\wire.exe -Algorithm SHA256.

How to use the Windows Powershell to find the file’s hash.

I hope this guide helped you easily find and verify the hash of a file on Windows!

The reason we made this guide is because we make a popular network security monitoring software for Windows called GlassWire. You can download GlassWire and try it free if you’d like.

Wikipedia also has a great page if you are looking to learn even more about file verification methods.
