What is KryptEY?

KryptEY is an innovative Android keyboard designed to facilitate secure end-to-end encrypted (E2EE) communication using the Signal Protocol. It empowers users to communicate independently, without the need for a server, regardless of the legal landscape or the E2EE status of the messaging platform.

Why KryptEY?

The motivation behind KryptEY stems from the growing concerns around the potential breaches of end-to-end encryption (E2EE). Laws, like the proposed EU chat control, threaten user privacy by enabling unauthorized third-party monitoring of E2EE content in popular messaging apps like WhatsApp and Signal. By integrating E2EE seamlessly through a keyboard, KryptEY simplifies secure communication without compromising privacy.

Features of KryptEY

• Messenger-independent E2EE using the Signal Protocol.
• Encryption and decryption of messages with ease.
• Dedicated text entry field to manage messages securely.
• Clipboard functionality for reading messages.
• Contact management built into the keyboard.
• Message log for viewing sent and received messages.
• Two sending modes: plain JSON (raw mode) and disguised in decoy text (fairytale mode).
• Verification of E2EE functionality via fingerprint.
• User-friendly QA view for assistance.
• Supports both dark and light themes.

How to Use KryptEY

Using KryptEY is as easy as pie! Imagine you have a special voice that only certain people can understand—a kind of secret language that scrambles everything you say so that only your friends can hear the real message. Here’s how you can get started:

1. Download the app from F-Droid, IzzyOnDroid, or GitHub.
2. Ensure your Android version is 8.0 or newer. If not, update your device.
3. Launch the app and grant the necessary permissions (for example, the vibrate function for key presses).
4. Begin using the keyboard in any messaging app to send secure messages effortlessly!

Troubleshooting Tips

If you encounter any issues while using KryptEY, here are some troubleshooting ideas:

• Make sure the keyboard is set as your default keyboard in device settings.
• If messages are not being sent, check your internet connection.
• Review your app permissions to ensure they align with KryptEY’s requirements.

Security and Limitations

KryptEY employs robust security measures derived from the Signal Protocol, which include:

• Elliptic curve X25519 with SHA-512 used for key agreement.
• AES-256 for message encryption, ensuring top-tier security.

However, it’s essential to note a few limitations. The app is primarily designed for 1-to-1 conversations, and while certain group messages can be handled, only designated participants will have access to the encrypted content.

Moreover, some restrictions apply with messaging apps like Telegram, which handle text as HTML rather than plain text. For optimal results, it’s recommended to use raw mode when opting for Telegram to avoid any decoding issues.

Additionally, the keyboard can only handle a maximum of 3500 bytes per message in certain applications, so it’s advisable to keep your messages concise.
