FluffyPuffin File Encryption Free is a Chrome add-on developed by downcryptaes. This free program allows you to encrypt any file less than 1MB to a chosen password, and it also automatically encrypts any download. With 256-Bit AES encryption, FluffyPuffin offers a simple and powerful tool for file encryption.

One of the main features of FluffyPuffin is its ability to automatically encrypt any file you download. When you download something for the first time, a page will load where you can input a password to encrypt the file. The password you enter will be stored until Chrome is closed, and any future downloads will be automatically encrypted using the stored password. However, you can disable this feature by unticking the "Enable Auto Encryption" checkbox.

Additionally, FluffyPuffin provides an encryption page where you can manually encrypt or decrypt any file on your computer. To access this page, simply click the extension icon to the right of the URL and click the "Open Encryption Page" button. From there, you can browse for files, enter the password, and encrypt or decrypt as needed.

FluffyPuffin File Encryption Free offers options such as enabling or disabling the add-on, enabling or disabling auto encryption, and choosing whether or not to delete the unencrypted original downloads. These options can be accessed by clicking on the FluffyPuffin icon to the right of the URL.

Please note that this free version of FluffyPuffin has a file size limitation of less than 1MB. For larger files, you may need to consider upgrading to the paid version.

Overall, FluffyPuffin File Encryption Free provides a convenient and secure way to encrypt your files and downloads within the Chrome browser.
