A registration is not required. As soon as you launch Achat for the first time, a keypair that represents your identity is automatically generated. Afterwards, you can start right away.
Conversations using Achat are encrypted locally and decrypted on your conversation partners devices. That means that a third party has no way to record or wiretap a conversation held over Achat, no matter whether said third party is a spy, a government agency or even the Achat developers.
Achat has a simple design and is easy to use. All important functions can be accessed with only a few taps.
The messages are encrypted with the AES-CBC algorithm using a key size of 256 bit. The identification of the users is being done using 4096 bit RSA key pairs, which are also used to negotiate an AES key. The encrypted messages are then transmitted to the recipient using a secure HTTPS connection to our servers.
