Encrypted SMS

का प्रयोग करें RSA सार्वजनिक कुंजी / आपके द्वारा भेजे जाने वाले प्रत्येक संदेश को सुरक्षित करने के लिए निजी कुंजी!

Do you think your SMS messages are safe?

No, absolutely not. Hackers are listening to the signals, criminals are stealing data, employees in the carrier may sell the data, and, devices may break. In China, criminals even can hijack the traffic and pretend to be your friend to converse with you with SMS.

So what can you do?

To secure the messages, first we need to encrypt the messages at the beginning, so no plain text is sent to the network. Second, we shouldn't send password to anybody else, passwords themselves are not secure.

This is what Encrypted SMS app is doing:

- encrypting with RSA + AES algorithm, no plain text is sent out

- RSA keys are generated by you on your device, they are only known to your device

- only public key is sent to your contacts, it is used to encrypt messages, but can not be used to decrypt messages

- private key is only on your device and never sent out, this ensures the confidentiality

- if your message is too long for RSA to encrypt, it will be encrypted with a randomly generated AES key using AES algorithm. The AES key will be encrypted with RSA public key and sent together with the message. This ensures efficiency.

Being cautious is the only way to deal with the security problem we are having today.
