Overview

Download on the App Store This is the support site for Disk Decipher, an app that allows access to encrypted (and unencrypted) disk images (e.g. TrueCrypt, VeraCrypt or DMG) from your iPhone, iPad and Mac.

Disk Decipher is copyright 2012-2025 Richard Huveneers.

Latest release

Version: 6.0.3

  • Added new Remote Storage Provider: Filen. Filen is fully Germany based and controlled, with high focus on security, so a perfect match for Disk Decipher. More information is available on the support site: https://disk-decipher.app/remote-storage/#filen
  • Localization improvements

Version 6.0 delivers a completely new File Provider!

If you use the Files integration, please read the documentation at https://disk-decipher.app/file-provider/

Any bugs in the new File Provider will be squashed during the 6.0.x updates, please report them at https://gitlab.com/huv/disk-decipher/-/issues (preferred) or by sending an email to the support address listed on https://disk-decipher.app/contact/

Warning

In April 2025, pCloud removed an important part of their API that allowed Disk Decipher to enable write support for disk images hosted on pCloud. As this part of the API is no longer available, Disk Decipher 6.0.4 introduces updated pCloud support, restoring read only access to your disk images hosted on pCloud.

Info

Disk Decipher for Mac has temporarily been frozen at version 5.5.5. This allows the new File Provider introduced in version 6.0 for iOS to settle during the 6.0.x update series before it appears in the Mac version.

Localization - Your help is needed!

The app user interface is currently available in English (default), Arabic, Brazilian Portuguese, Czech, Dutch, German, Greek, Hungarian, Polish, Russian, Simplified Chinese, Slovak, Spanish, Turkish, Traditional Chinese and Ukrainian. To provide the best user experience, it would be great to extend this list with more languages.

Please contact me if you can help by translating the user interface into your native language.
