Galaxkey is an application for viewing Galaxkey Secured Documents and sending secured emails. When someone sends you Galaxkey secured file with the extension .gxk or sends you a Galaxkey secured email, the Galaxkey app provides a simple file-handling tool to open the Galaxkey secured files. A user can open a .gxk file in the Galaxkey app from emails or any file storage on the mobile device. The app authenticates the user with the cloud service and then decrypts and displays the contents of the file. If the contents of the Galaxkey file are an email, then the Galaxkey App will display the email along with its attachments. The app does not store any information of the decrypted file on the device so your data is still secured. The app also lets the user respond to emails that are opened in the app. The mail is sent securely using the users email account. Users can also create and send new secured emails using their Galaxkey account. The user needs to be registered with Galaxkey to be able to open and view Galaxkey secured files.
