About Crypto Messenger

Secure end to end encrypted messaging for those who privacy matters.

Crypto Messenger is end-to-end encrypted messaging application. It's a part of my Cryptography application and all its workings are describe at my website. It's not intended to replace any bigger messaging applications. You can find link to documentation at app's about dialog.

Understanding the bigger picture

Don't use Crypto Messenger if you use it for normal chatting just like instant messaging platforms. Don't use this app if you require that your conversation messages stays stored forever or long time during to update flow. I cannot guarantee that conversations stay active for ever, so have a backup route to give your recipient a new uid other way. Use Crypto Messenger if your requirement is to send true end to end encrypted messages without need to really store messages forever. Think Crypto Messenger like messaging that "never took place". Crypto Messenger is working as a true working demo for my Cryptography application.
