I am searching for a way to encrypt images before saving them on server (private folder) and decrypt it when node is rendered for roles that have views permissions.
I found the Encrypted Files module, but it's not covered by Drupal’s security advisory policy.
I installed and configured both the available versions (1.x , 2.x). It seems files are encrypted successfully, but I can see the image when I view a node or in the image preview widget because it seems it can't be decrypted.
How can I use this module? Is there any video guidance? I searched Internet but I didn't find any useful video.
