Insular vs KryptEY
Side-by-side comparison of two open source alternatives
Insular
Insular is a FLOSS fork of Island. With Insular, you can: Isolate your Big Brother apps Clone and run multiple accounts simutaniuosly Freeze or archive apps and prevent any background behaviors Unfreeze apps on-demand with home screen shortcuts Re-freeze marked apps with one tap Hide apps Selectively enable (or disable) VPN for different group of apps Prohibit USB access to mitigate attacks with physical access If your device is incompatible or not encrypted, you can skip this limitation manually. Please refer to the XDA post for details. To uninstall and remove Insular completely, please first "Destroy Insular" in Settings - Setup - Click the recycle-bin icon besides Insular. If you have already uninstalled Insular app, please "Remove work profile" in your device "Settings - Accounts". PERMISSIONS DEVICE-ADMIN: Device administrator privilege is required to create the Insular space (work profile), which serves as the fundamental functionality of Insular. It will be explicitly requested for your consent. PACKAGE_USAGE_STATS: Required to correctly recognize the running state of apps. It will be explicitly requested for your consent. We will never collect any data and Insular have no Internet permission. Please read our privacy policy for more details. Differences from Island all blobs (gms, crashlytics, etc) are removed to comply with F-droid's policy Internet access of this app is removed because we just don't need it All features are preserved and will be synced upon Island's updates
KryptEY
Communicate securely and independent, regardless of the legal situation or whether messengers use E2EE. No server needed. #ChatKontrolleStoppen Why KryptEY? Breaking of end-to-end encryption (E2EE) by laws such as the planned EU chat control is an ongoing issue. Content in messengers that use E2EE, such as Whatsapp or Signal, could thus be monitored by third parties. E2EE is often, but not always, standard in messengers. There are proven methods for E2EE such as PGP. However, these methods are sometimes cumbersomely integrated and require a lot of effort to use. KryptEY is an Android keyboard that implements the Signal protocol. The keyboard works messenger-independently and both the X3DH Key Agreement Protocol and the Double Ratchet Algorithm work without a server, thus it enables a highly independent use of the protocol. Features Based upon Simple Keyboard ( https://github.com/rkkr/simple-keyboard ), KryptEY adds a view above the Keyboard for the E2EE functionality. * use E2EE through Signal Protocol in any messenger * encryption/decryption of messages * enter message through separate text field in keyboard * use clipboard to read messages * manage contacts in own contact list in keyboard * message log to view sent/received messages * send messages as plain JSON (raw mode) or hidden in a decoy text (fairytale mode) * verification of E2EE functionality via fingerprint * Q&A View for questions * dark & light theme See https://github.com/amnesica/KryptEY/blob/master/KRYPTEY.md for further information on how KryptEY is working. Security The existing security properties for the Signal Protocol are also valid for the keyboard. Limitations The keyboard was designed as a POC and only allows 1-to-1 conversations. However, the application can also be used in a group chat to a limited extent. Here, a message can be directed to a specific chat partner and not to all people. Other participants of the group chat cannot decrypt the message. Text messages in Telegram are getting copied as HTML and not as plain text. When decoding the message with the fairytale mode the copied message is compromised and can't be read properly. Therefore, it can't be decoded at all. However, the raw mode works properly. When using KryptEY with Telegram we recommend the raw mode. Some messengers like Threema only allows up to 3500 bytes per message. Therefore, different character input limitations apply. To stay under the 3500 bytes limit, only 500 characters are allowed for raw and fairytale mode. For convenience these limitation applies for all messengers. Demo For a demonstration on how KryptEY is used see https://github.com/amnesica/KryptEY/tree/master#demo KryptEY was created by mellitopia and amnesica.
