I have around 2 GB of family photos in one of the cloud storage. I want to keep these photos encrypted and at the same time should be able to run a slideshow and view them locally on my PC or online. I am looking for any service which provide on-the-fly password based decryption. I don't have an external HDD and no plan to buy soon. I also don't want to keep photos synced with my laptop. Photos were just consuming too much space. Regularly photos are automatically uploaded to the cloud from my phone and later I arrange them from the web interface. I want photos to be backed up to the cloud encrypted and when needed I should be able to perform on-the-fly decryption and run slideshow. Please suggestion any solution for this.
