Offline AES encryption?

Posted 14 August 2017 - 11:16 AM

Hi, I want to encrypt some text using AES but I'm cautious about entering the information into an online website. Does anyone know how I can download some open source AES program / website and run it locally on my PC?

Thanks.

If you have access to a Linux box, you could install gpg2, which allows for AES encryption and will work fully locally (after it is installed).

I don't have linux installed, I could install a virtual machine but maybe I#ll try the github search first.

Thanks.

If you are on any recent version of Windows, you'll have the .NET Framework. It has AES encryption in it. For light usage, you can use PowerShell to get access to the classes exposed in the framework. Again look in github for "AES Powershell".

If you want to write C# directly, then use the same classes that PowerShell would be using: AesCng, AesCryptoServiceProvider or AesManaged as described here: Aes.

The middle one is just a wrapper around the older AES crypto service provider that is built into Windows. If you don't want to go through the wrapper, you'll need to write some C or C++ code.

The first one is also a wrapper around the newer AES crypto service provider thas is also built into Windows.
