Description
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.
What does it mean for public key and private key?
Usual way of password encrypting: (the way NOT used in this app)
Sender: Hello, this is the message I want to share with you, I've locked it in the box and here is the key to unlock it!
(locked box) + (key)

|
|<-thief: oh this is key to the lock, let me check if money is inside!
|<-courier: I am just interested in what is inside? I have a locked box but I have the key too!
|<-hacker: a locked box with a key? Let me tell you hackers are powerful!
|
|
v
Receiver: Ok user this key to unlock the box. (but I don't know it is already unlocked many times!)
Public key / private key encrypting: (the way this app is using)
Receiver: Hello, if you have message for me, please use this locker! I will keep the key with myself!
(open locker)
|
|
|<-thief: a locker without key? useless. It is sold at convenience store at only 30 cents! plus the key!
|<-courier: a locker without key? I should do my work so I get salary.
|<-hacker: a locker without key? not interested
|
|
v
Sender: Ok got the locker
~~~~~
Sender: Hello, I have a message for you, locked with the key you sent me!
(locked box)
|
|
|<-thief: a locked box without key??? Damm it! Where is key?
|<-courier: a locked box without key??? I am honest person
|<-hacker: a locked box without key??? I can show my power somewhere else
|
|
v
Receiver: Great! I have the key to unlock it!
(find the key to unlock it)
Being cautious is the only way to deal with the security problem we are having today.

Questions & Answers
Q: What is an APK File?
A: Just like Windows (PC) systems use an .exe file for installing software, Android does the same. An APK file is the file format used for installing software on the Android operating system.
Q: If I install an APK from this website, will I be able to update the app from the Play Store?
A: Yes, absolutely. The Play Store installs APKs it downloads from Google's servers, and sideloading from a site like ApkClean.net goes through a very similar process, except you're the one performing the downloading and initiating the installation (sideloading).
As soon as the Play Store finds a version of the app newer than the one you've sideloaded, it will commence an update.
Q: Why ApkClean.net can guarantee APK 100% safe?
A: Whenever someone wants to download an APK file from ApkClean.net, we'll check the corresponding APK file on Google Play and allow user download it directly (of course, we'll cache it on our server). If the APK file does not exist on Google Play, we'll search it in our cache.
Q: What are Android App permissions?
A: Apps require access to certain systems within your device. When you install an application, you are notified of all of the permissions required to run that application.
Don't hesitate to contact us if you have any questions or concerns.
