About this app

CryptoContainer is an Android app for working with VeraCrypt containers and AESCrypt-encrypted files on stock Android 14 devices without requiring root.

VeraCrypt

CryptoContainer can create new VeraCrypt volumes and open existing ones. It supports both Standard and Hidden volumes, with support for VeraCrypt default encryption options including AES, Serpent, Twofish, and cascade modes, along with supported hash options such as SHA-512 and Whirlpool.

When creating a volume, you can choose the container file, size, filesystem, password, PIM, and optional keyfiles. Hidden volumes are supported with separate hidden size and hidden credentials. Supported filesystems include FAT, exFAT, and NTFS. NTFS is available with stock-device support, and the app indicates when a mounted container is operating read-only.

Once a container is opened, CryptoContainer provides a built-in explorer window designed for browsing and managing the contents of the mounted container. You can navigate folders, create new folders, add files, add multiple files at once, import folders recursively, extract files, extract folders recursively, rename files and folders, copy, cut, paste, delete, and multi-select items for bulk operations. Containers can also be closed directly from the app, and mounted sessions are cleared when the app is terminated.

CryptoContainer also integrates VeraCrypt containers with Android sharing and file handling. You can open .hc files directly in the app, or share a container file into CryptoContainer to populate the VeraCrypt container field automatically. Files shared from other apps can be imported into an already mounted container. If no VeraCrypt container is mounted, the app blocks the action and shows a clear error message instead of failing silently.

AESCrypt

CryptoContainer also supports AESCrypt file encryption and decryption. The AESCrypt section is split into separate Encrypt and Decrypt actions for a simpler workflow.

For encryption, you can choose a file, enter and confirm a password, and save the encrypted output to the location you choose. If multiple files are selected through Android share, CryptoContainer first packages them into a ZIP archive and then encrypts the ZIP as a single AESCrypt file.

For decryption, you can choose an .aes file or other encrypted input, enter the password, and select the output location. When decryption succeeds, the app preserves the original filename whenever possible, shows the output file name and saved path, and provides options to open the file or open the output folder. Decrypt and encrypt operations support Android share flows, so files can be sent directly into CryptoContainer for AESCrypt encryption or decryption.

Integrated Android workflow

CryptoContainer is designed to work with Android’s document and share systems. It supports direct open for .hc VeraCrypt files and .aes AESCrypt files, and supports Android share actions for:

- Mount as VeraCrypt Container
- Encrypt Using AESCrypt
- Decrypt Using AESCrypt
- Share Into Open VeraCrypt Container

Security and session behavior

Passwords are treated as secure input, with masked entry and optional reveal controls. Clipboard-cleared password handling is included where used, and cached passwords are session-only. When the app is closed or terminated, open container sessions are closed as well.

CryptoContainer focuses on practical encrypted file management on Android
while keeping everything usable on non-rooted devices.
