ShipiboConibo ,

File support fixed! But...

I’m updating my review for two reasons. #1 is that file support was added, and I can now easily import a LUKS container from iCloud or Nextcloud/ownCloud/etc.. However, I was disappointed to discover, after importing my containers, that they failed to mount. After reading on the website I conclude that there is no support for ext4 formatted containers. Having a journaled FS in my container has saved me from file corruptions on several occasions. On my computers I run fsck on the decrypted volume every time I mount the container, and it’s not uncommon for it to find problems and fix them. You might wan’t to consider added a step like that as well. Not that I’m an expert on any of this, though. At the least, could you please add support for common open-source filesystems, such as ext4? I’ve been patiently waiting and watching as this app evolves, and I was sure it would where I needed it to be for my use-case in this last update... I’d be so grateful if you could make it compatible with containers that house an ext4 filesystems! P.s. I tried to find an email on your website but didn’t see one, the feature request form did not have a place to write in a feature either, only select one of those in the list. Thanks!

Alright app

App works fine, but does not have many features. You are unable to create crypts (you must create with 3rd party then import. I used VeraCrypt and sent the file through Google Drive), you are unable to delete directories (folders), you cannot move files around, you cannot search for items (no search bar/function), and you cannot choose how items are sorted (date/alphabetical/size/etc). The app feels a bit restrictive, but it does its job. I’d recommend this app as more of a crypt viewer than a crypt editor.

On the plus side, this app’s privacy policy is great, it supports many file types, and it is very secure (the second you close the app it dismounts the drive).

Of the two apps for file decryption on the AppStore right now, I would recommend this app. While this app is missing a lot of features, it has a much better privacy policy than the other, and this app does not (to my knowledge) have ties to the Chinese government like the other one.

Overall, missing features, but secure. 4/5.

Developer Response ,

Good feedback, thanks. I will add these items to the feature request page (https://disk-decipher.app/feature-requests/) to allow everybody to vote on them.

The focus of the 3.x release is the iOS File Provider which will allow you to do exactly these operations once write support is implemented in the iOS File Provider. This is definitely on my todo list for this year.

Great Preview Feature

I really like 3 features. Please keep up the great work! 1) the Disk Decipher settings default to the most secure settings and Disk Decipher makes efforts never to place unencrypted data into device memory. I’m a security professional and these are features I look for. 2) The preview feature allows me see the contents of my pdf and xlsx spreadsheets without opening them on the device. This is wonderful because most of the time I just need to see the information, not edit it. But Disk Decipher also gives me the option of opening the file in the app on my iPad or iPhone so I could edit it if I want. I’m a PC user so I transfer the VeraCrypt container from my PC to my mobile devices using a USB drive and store the container in local files. Then I open Disk Decipher and import the local container. 3) I also like that Disk Decipher can access containers stored on iCloud, OneDrive, and Google Drive as it gives a lot flexibility and options, even though at this time I’m not using these for my encrypted data.
