<h2>What is Safe Chat?</h2>
|
||
|
|
<p>Safe Chat is a chat program to protect your privacy. It is
|
||
|
|
designed to be extremely easy to use, with all cool features,
|
||
|
|
but with highest security through strong encryption. For more
|
||
|
|
information, open «About Safe Chat» in the menu
|
||
|
|
(<img style="height: 1em; border: 2px solid green;
|
||
|
|
vertical-align: text-bottom; background-color: green"
|
||
|
|
src="images/menu.svg" />) above.</p>
|
||
|
|
<h2>Never forget your Password!</h2>
|
||
|
|
<p>This messenger is absolutely secure. But on the other hand,
|
||
|
|
that means, no one except you knows your password. No one can
|
||
|
|
read your messages exept you, not even our administrator. It
|
||
|
|
is technically impossible to restore a password. You would
|
||
|
|
have to delete your account and create a new one. In that
|
||
|
|
case, all messages are lost.</p>
|
||
|
|
<h3>Keys and Password</h3>
|
||
|
|
<p>Safe Chat internally uses OpenPGP for public/private-key
|
||
|
|
encryption. Your password is not transfered to the server and
|
||
|
|
not stored, it is used only to create and encrypt your private
|
||
|
|
key. There are two keys, a secret private key, that is stored
|
||
|
|
in the browser (or app) on your computer, encrypted with your
|
||
|
|
password and not sent to the server. There is also public key,
|
||
|
|
which is sent to the server and used by other users to encrypt
|
||
|
|
messages that only you can read. You can backup and restore
|
||
|
|
your keys and setings to and from a file. This is the only way
|
||
|
|
to transfer your account to another browser or to computer. Do
|
||
|
|
not delete your browser's local storage unless you have backed
|
||
|
|
up your keys.</p>
