Code word:

This is an experimental post for those who value the security and privacy of communication, and lack of Spam.

Even when the information is secret protocols (HTTPS, SSH) there is a probability of interception and compromise (reading) data. This is illustrated by the following figure which shows that the "weak link" here is the serveron which the data is stored in the clear. The human factor, back-doors, hacking, etc. can compromise the stored information. Also, there is evidencethat the protocols protect data is not absolute.
Our mail is devoid of all these shortcomings. It is based on symmetric Hash-Mask algorithm, in which encoding and decoding data is performed ONLY on starone client, specifically the browser. This ensures that the interception of data at any stage: communication channel, server, etc., will not lead to their compromise. The secret secure — to the openness and simplicity of the algorithm and scripts, and hence in the full custom control of the entire process to preserve the secrecy of their data.

How to send a letter?
In the "Subject" field, type any unique name or e-mail recipient. Enter the message text and "Code word" — characters, who then gives it to the recipient. Click on "Encrypt" and then "Send".

How to get a letter?
In the Subject field enter a title for Your correspondence or Your e-mail (by agreement with the sender). After pressing the button "Search" You will be found the letter on this topic that are stored on the server. Select one of them, for example, the most recent, enter the "Code word" and click "Decrypt". If done correctly, the window will appear the text of the letter.

Do I need any registration?
Registration is not required, completely anonymous email.

How to ensure that decryption/encryption of data happens only in the browser?
You can verify this if you get the email, disconnect from the Internet and then enter code word and decrypt the text. Similarly, in the reverse order, you can proceed with sending the letter. Also, you can workout in the encryption of the texts in Rosedale "Sandbox" (off-line).

Advanced users can look through the scripts and the code in them is fully open. Used: jQuery, JavaScript-MD5 , and our scriptthat encrypts/decrypts the text and maintains the interface with the user. For clarity, we used simple and intuitive to use JavaScript and jQuery.

How to pass a "Code word"?
The code word is a key element of the show. It is necessary to provide the recipient with an independent communication channel, e.g. via SMS message. If this condition is met, any other way, once reading the message with You from the monitor screen, it is impossible to intercept and decipher!

How to choose a "Code word"?
The code word can consist of digits and Latin characters. Cyrillic and special symbols also theoretically work, but practically not yet tested everywhere. For example, You can use a word known only to You and to the recipient, or, if the correspondence involves several participants — all of them. The number of symbols of a code word is unlimited.

How to choose the "Theme" of the letter?
As "Topics" best use of e-mail. But it can be any combination of numbers and letters. It is important that this combination was possibly unique. The number of characters of the subject is unlimited.

What if the title of my "Theme" will coincide with somebody else's?
Nothing terrible will happen: anyway to decipher the text of the letter without knowledge of the code words will not work.

What is the difference between "Theme" and "Code word"?
A theme is a name of a correspondence on the same issue, either with the same party. In the second case, as the subject of entered e-mail that person. In the same topic, the code word may remain constant or be changed periodically (by agreement of the parties). The theme can be transferred to the receiving party via an open communication channel.

The code word you need to convey definitely an independent communication channel. The same codeword may be used by the user in different themes.

How many people can participate in the conversation on one "Theme"?
As much as necessary. It is important that they all knew the name of the theme and the code word.

What characters can be used in the text of the letter?
The text of the letter can contain numbers, Latin, Cyrillic and special symbols.

Can I transfer files?
Yet. Text only.

How many mail messages are stored on the server?
One month.

In what form are my messages on the server?
A real world example. In the "Send" was introduced:

  • topic - Test
  • text messaging - ping!
  • code word - Lighters

As a result, the server has been created the following file fef89e41320e80e4b84822b8df142349_1404124604. From the example we can see that the file contents are encrypted, and even his name is a hash from which it is impossible to understand the name "Themes".

I want to send encrypted text letters through other channels of communication. What to do?
In the "Sandbox" encrypt the text, and in this form pass them on to other channels. Your caller can enter this text in the box in the same section and decode it. This can be done in off-line mode (without network access).

In what OS or browser e-mail works?
In any OS and any modern browsers.

As for your post about SPAM?
Here it is fundamentally impossible! There is no point in sending a letter the recipient to decipher:)

Here you can workout in the encryption/decryption of text.
The resulting encrypted text can be sent, for example, a normal unsecured email.
Inserting encrypted text in the lower window it will again be decrypted.
