Requests and issues
If you have feature requests, please file them in the issue tracker or contract one of the authors directly.

Features alpha-1 (Proof of concept)

  • Create Diffie-Hellman/AES keypair.
  • Send public key to a contact in your address book.
  • Receive and store public keys.
  • Send and receive encrypted messages. We use ‘double’ RSA encryption to guarantee both the sender and the receiver.
  • Encrypt messages stored in outbox using your own public key, so you can read your own sent messages.

Beta-0.9 (First public release)

  • Better interface for sending public key.
  • Better usability by giving more and better notifications to the user.
  • Better interface for accepting public keys.
  • Friendly user interface. Icons in menu.
  • Never show messages in encrypted form, show alternate text instead (i.e. ).
  • Never show public keys (as happens in the inbox and notification bar in alpha-1).
  • Use symmetric key for the actual data and a asymmetric algorithm to generate the symmetric key.
  • Send public key in binary form so we don’t need base64.
  • Send messages in binary form so we don’t need base64.
  • Possibility to send normal (non-encrypted) messages to receivers that have a public key present.
  • Option to encrypt private key. Ask for unlock pattern when trying to access. Store in memory till standby?
  • Stored messages encrypted with a password and a pincode as a salt. The password will be stored in memory (encrypted with the incode), and in combination with the pincode, messages can be decrypted and read.
  • Settings option to ‘logout’ when the screen goes in standby.


  • Export/import public keys to/from SD card
    • Option to send own public key to all imported public key numbers.
  • In manage publickeys option to forward public keys to other people.
  • Selfdestruct (on sms)
  • After generating a new keypair, option to send new public key to all existing public key numbers
  • When receiving a new public key, option to reply by sending own public key
  • Menu option to logout.
  • When typing a text message, a counter that shows the size of the encrypted message
  • Share public keys with QR-codes

Wishlist future

  • Get academic backup (proof) for our implementation.
  • Localization (Help wanted! See Contributing)
