UEncrypt - Universal End to En

An end-to-end encryption tool helps you encrypting messages. It prevents your chats from being monitored by third-party authorities.

Here's how it works:

The application will generate a 4096bit RSA key while initializing. You can send your public key to your friend, and install the one your friend send to you. After you installed your friend's public key, you will be able to encrypt your messages with that key. The message will first be encrypted with a random key using the AES algorithm, then the random key will be encrypted using the RSA algorithm with your friend's public key. After that, only your friend can decrypt the message.

Now we only have message encrypting/decrypting function available on Android, we will implement more functions later on.
