Simple, standards-based file encryption on iOS with handy decryption but limited workflow

AES Crypt for iOS offers robust AES-based decrypting (free) and optional in-app encryption with cloud integration and biometric protection, but users report limited batch/workflow features, occasional crashes with large files, and a mixed App Store rating, making it best for occasional secure file transfers rather than heavy daily use.

AESCrypt for iOS provides a practical solution for decrypting and previewing files encrypted with AESCrypt.com directly on your iPhone or iPad. The application seamlessly integrates with popular services such as Dropbox, Drive, and email clients, enabling users to open encrypted files with ease.

The in-app upgrade introduces the capability to encrypt files directly on your device, enhancing security for documents, photos, and other data before sharing them securely to cloud storage services. This feature set aims to streamline workflow while maintaining robust encryption standards.

Utilizing the industry-standard Advanced Encryption Standard (AES), AESCrypt ensures strong, cross-platform security compatible with Windows, macOS, Linux, and mobile operating systems. This setup offers an effective means for backing up sensitive information either locally or to the cloud, with straightforward controls for protection and management.

Decryption features include adding AESCrypt as an “Open In…” option for .aes files, enabling access from Dropbox, Drive, email, and other sources.
Decrypted files can be stored within the app for viewing or exported to other applications.
Quick actions such as renaming or swipe-to-delete facilitate efficient file management.
The app performs a DoD 5220.22-M compliant secure wipe prior to deleting files for enhanced privacy.
Supports previewing a variety of common file types including PDFs, images (JPG, PNG), videos (MOV), and text files.
Displays relevant file details such as decryption date and size for user reference.

The premium upgrade introduces additional functionalities geared toward encryption:

The ability to encrypt files directly on iOS devices and store them securely within the app.
The option to capture photos via camera and encrypt them immediately for secure storage.
Integration with “Open In…” functionality across various file types, allowing encryption directly from applications like Pages, Numbers, Keynote, and others.
Export options for encrypted files and photos to multiple cloud services including Dropbox, Drive, and iCloud.
Support for biometric authentication through Touch ID and Face ID to safeguard stored data inside the app.

Additional notes include the following:

The app supports decryption exclusively of files encrypted with AESCrypt.com or this application itself.
Encryption features are accessible only after purchasing the in-app upgrade.
Files encrypted by other software or methods are incompatible with decryption through this app.
Support requests and feature suggestions can be directed to the Discussion Forum at AESCrypt.com.

No single‑session password caching: users must reenter passphrases frequently (cumbersome for multiple files)
No batch encrypt/decrypt available yet (listed as a near‑term roadmap item)
App only decrypts files created by AESCrypt.com or this app — will not handle files encrypted by other tools/methods
Workflow for editing encrypted documents is clumsy: requires export/edit/import cycles per file
Reports of crashes or instability with very large files (~1GB) when deleting or removing from lists
Limited advanced features (no keyfile support, no Apple Shortcuts integration, limited search/sort) — some are only planned
Some users report low satisfaction: App Store rating around 2.8/5 with complaints about usability
Subscription details, automatic renewal, and Apple billing apply (must cancel within Apple ID settings to stop renewal)
Requires relatively recent iOS/iPadOS (15.1 or later), limiting use on older devices

FAQ

What is AES Crypt for iOS and what does it do?

AES Crypt is an iPhone/iPad app that uses the industry-standard Advanced Encryption Standard (AES) to decrypt (free) and, with an in‑app upgrade, encrypt files and photos on iOS. It enables secure previewing, storage, and sharing of files encrypted with AESCrypt.com or by the app itself.

Which features are available for free and which require the in‑app upgrade?

Free: decrypt .aes files opened via “Open In…”, save decrypted files in the app for preview/export, preview common file types (PDF, JPG, MOV, PNG, TXT, etc.), rename/delete with quick actions, and a DoD 5220.22‑M secure wipe on deletion. In‑app upgrade (paid): encrypt files and photos on the device, add AES Crypt as an “Open In…” option for all file types (to encrypt from other apps), export encrypted files to cloud apps, and enable biometric protection (Touch ID/Face ID) for the app.

Which encrypted files can AES Crypt decrypt?

The app decrypts files encrypted with AESCrypt.com or files encrypted by this iOS app. It will not decrypt files encrypted by other encryption methods or incompatible software.

How do I open encrypted .aes files from cloud or email apps?

Use the cloud/email app’s Share or Export menu, choose “Open In…” (or the Files app), and select AES Crypt. The file will be imported into AES Crypt where you can enter the passphrase to decrypt and preview or export the decrypted file.

What platforms and file types are supported for cross‑platform use?

AESCrypt uses AES (compatible across Windows, macOS, Linux, and mobile) so files created with AESCrypt on other platforms can be decrypted in the iOS app. The app previews most major file types (PDF, images, video, text, etc.). Note: only files encrypted with the AES Crypt format are supported.

Is my data protected inside the app? What about biometric unlock and secure deletion?

Biometric protection (Touch ID/Face ID) is available as part of the in‑app upgrade to protect access to in‑app files. When you delete files, the app performs a DoD 5220.22‑M secure wipe. Files saved in the app remain local unless you export them to other apps or cloud services.

What are the subscription or purchase terms and how do I cancel?

Encryption capability is provided via an in‑app upgrade/subscription. Pricing and duration are shown in the app under Settings → “AES Crypt (Paid Full Version)” at purchase. Payment is charged to your Apple ID, and subscriptions auto‑renew unless canceled at least 24 hours before the end of the current billing period. Manage or cancel subscriptions in your Apple ID account settings.

What are common limitations and known issues?

Current limits include no batch encrypt/decrypt (single‑file operations only), no keyfile support (planned), and the app only works with the AES Crypt file format. Some users have reported crashes when deleting very large files. The roadmap lists improvements such as multi‑select, saved passphrases, keyfile support, and Apple Shortcuts integration.

What iOS version and device requirements are there?

AES Crypt requires iOS/iPadOS 15.1 or later and is designed to run on iPhone and iPad (App Store listing shows app size and device compatibility).

How do I get support, report bugs, or request features?

For support or feature requests email [email protected] or visit the AESCrypt discussion forum at AESCrypt.com. The app website also lists a support/contact section and a roadmap where you can suggest features.
