<p><b>What is going on?</b><br>Your files have been encrypted using strong reliable algorithms RSA-2048 and ChaCha20 with an unique private key for your system</p>
<p>You can read more about this cryptosystem here: <a href=https://en.wikipedia.org/wiki/RSA_(cryptosystem)>https://en.wikipedia.org/wiki/RSA_(cryptosystem)</a></p>
<p>The only way to recover (decrypt) your files is to buy decryptor with the unique private key</p>
<p><u>Attention! Only we can recover your files! If someone tell you that he can do this, kindly ask him to proof!</u></p>
<p>By us you can decrypt one of your files for free as a proof of work that we have the method to decrypt the rest of your data.</p>
<p>In order to either buy the private key or make test decryption contact us via email: <br> <u><b>Main e-mail: [email protected]<br>Reserve e-mail: [email protected]</b></u>
<p>Remember to hurry up as email address may not be available for very long as soon as law enforcements of different countries always trying to seize emails used in ransom companies
<p>If you are willing to pay but you are not sure knock us and we will save your e-mail address. In case the listed addresses are seized we will write you from the new one</p>
<p>Below you will see a big base64 blob, you will need to email us and copy this blob to us.<br>you can click on it, and it will be copied into the clipboard.</p>
<p>If you have troubles copying it, just send us the file you are currently reading, as an attachment.</p>
