Restoration of your data with our software requires a private key which only we possess. ========================================================================================================================== To confirm that our decryption software works send 2 encrypted files from random computers to us via email. You will receive further instructions after you send us the test files. We will make sure you retrieve your data swiftly and securely and your data that we downloaded will be securely deleted when our demands are met.
