Encrypted Chat

Utilizza la chiave pubblica RSA / chiave privata per proteggere ogni messaggio che invii!

We use electronic ways (instant messengers, emails, sms, etc) to communicate every day, but are they safe?

No, absolutely not. Disguised hotspots are hijacking your conversations, hackers are cracking servers to steal sensitive information, big data tools are constantly scanning every email/chat to find anything interesting, and in some country, government forces software and hardware makers to collect information for them, in the name of public security.

So what can you do?

No worry now, using Encrypted Chat is the correct way. This APP secures information with RSA encryption, an algorithm which has been mathematically proven safe. It uses two different keys: the public key to encrypt messages, and the private key to decrypt message. Unlike usual password protection, private key is never sent out and exists only on the device that generated it. So nobody else has the private key and nobody else can decrypt the message except you!

An illustrate of the RSA encryption method:

YOU: Hello, if you have message for me, please use this locker(public key)! I will keep the private key with myself!

(An open locker(public key))

|<-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

YOUR CONTACT: Ok got the locker(public key)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

YOUR CONTACT: Hello, I have a message for you, locked with the locker(public key) you sent me!

(locked box(encrypted with public key))

|

|

|<-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

YOU: Great! I have the private key to unlock it!

(find the private key to unlock it)

So you can see the advantage over usual password encryption:

-- does not send out "password" that can be used to decrypt message

-- private key is long number (1024 bits or more) and almost impossible to crack with brutal force

This APP is an extension of the Encrypted SMS APP and provides similar encryption service but different in:

-- network traffic is used instead of SMS text, may help you reduce SMS cost

-- encrypting images are possible now

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