CryptoGallery

CryptoGallery is a simple way to store and view encrypted images in android.

Overview

Images are copied over from the android file-system, where they are then encrypted with a user-chosen symmetric key, using java's default implementation of AES. The encrypted images are then stored in internal storage, and thumbnail data is encrypted before being stored in the SQLIte database.

Usage Notes

Before using, please keep in mind the following:

It is highly recommended to back-up any images before importing them to the app. If your key is lost, or a bug occurs, you will lose all saved data.
Currently the app is based around the standard java library implemenation of AES-128 CBC. There are later plans to upgrade to AES 256.
Deleting photos
- Multiple photos/albums may be deleted through a long press, followed by pressing the appropriate deletion button
Exports
- Exporting photos or albums is done in a similar way to deletion; simply long press the desired item and press export
- Exported items are located in a plaintext .zip folder inside the phones external download directory.
Performance
- When dealing with a large number of entries, the UI can experience some lag. Working with albums of less than 150 photos is recommended.
- After importing a large set of photos, the album should be refreshed, as it may take several seconds for the operation to finish.

Building from source

The source may be obtained either through git clone https://gitlab.com/Isometricmap/PhotoCrypt.git, or by downloading and unzipping the file.

Open the source with android studio, then click Build -> Build APK(s).

Dowloading the APK

If building from source is not an option, you can use the APK [here https://gitlab.com/Isometricmap/CryptoGallery_APK ]. It includes both the signed APK, as well as the signing certificate fingerprints.

Planned

Exporting photos in an encrypted state, including a shell script to automatically handle decryption
Upgrading encryption
- An upgrade to AES 256
- Allowing the user to export an encrypted zip in combination with a bash script to decrypt it.
General UI improvements
- This includes a status bar for exporting/importing photos.
