Enigma Messenger is a simple, powerful and secure program for Windows that enables you to exchange instant messages with other users. What is more, all communication is heavily encrypted and data transfers can even self-destruct. It is necessary to mention that groups can hold up to one hundred thousand members. Both audio and video calls are supported.

Main capabilities

Among notable features of this application we should note the possibility to sync all your messages across your portable and stationary devices. You are able to send direct and group messages, as well as files. All data that you share is end-to-end encrypted by default. The outgoing messages are stored on the server, while the keys remain on your computer, ensuring complete confidentiality.

Powerful encryption

The protection is based on 256-bit symmetric AES and 2048-bit RSA encryption, along with Diffie-Hellman secure key exchange. In addition, your phone number is hidden to everyone, thus you can prevent others from finding you by configuring corresponding privacy settings. It is also possible to set a separate unlock password for the program to avoid leakage of personal data. Alternatively, you may try similar utilities like WhatsApp, Line or Skype.
