| Who holds the keys | You hold the keysShow detailsHide detailsMEGA says files are encrypted on your device with a random key per file, and file names, folder names and thumbnails are encrypted too. File sizes, the folder structure and the order of file versions stay readable to MEGA. The web version loads its encryption code from MEGA's servers on every visit, unless you use MEGA's extension for Chrome or Edge. | You hold the keysShow detailsHide detailsTresorit says files, file names and subfolder names are encrypted on your device, each with its own key. The names of top-level folders, their size and member list, and file size, type and creation time are not end-to-end encrypted.
