===================== [PersonalKey] =====================

===================== [PersonalKey] ===================== 
The singing of the sparrows, the breezes of the northern mountains, and the smell of the earth. I'm sitting on a wooden chair next to a bush tree, I have a readable book in my hands and I am sweating my spring with a cup of bitter coffee. Today is a different day. 
Behind me is an empty house of dreams and in front of me, full of beautiful white roses. 
To my left is an empty blue pool of red fish and my right, trees full of spring white blooms. 
I drink coffee, I'll continue to read a book from William Faulkner. In the garden environment, peace and quiet. My life always goes that way. Always alone without even an intimate friend. 
I have neither a pet nor a friend; I am a normal person with fantastic wishes among the hordes of white rose flowers. Everything is natural. I'm just a little interested in hacking and programming. My only electronic devices for this project are for iPhone and iPod touch. 
Believe me, my only assets are the white roses of this garden. 
I think of the days and write at night, the story, the poem, the code, the exploit or the accumulation of the number of white roses, and I say to myself that the wealth is different friends of different races, languages, habits and religions, Not only being in a fairly stylish garden with full of original white roses. 
Today, I think deeply about the decision that has involved my mind for several weeks. A decision to freedom and at the cost of unity, intimacy, joy and love and is the decision to release the white roses and to give gifts to all peoples of the world. 
I do not think about selling white roses again. This time, I will plant all the white roses of the garden to bring a different gift for the people of each country. No matter where is my garden and where I am from, no matter if you are a housekeeper or a big company owner, it does not matter if you are the west of the world or its east, it's important that the white roses are endless and infinite. You do not need to send letters or e-mails to get these roses. Just wait it tomorrow. 
Wait for good days with White Rose. 
I hope you accept this gift from me and if it reaches you close to your eyes and feet. 
Thank you for trusting me. Now open your eyes. Your system has a flower like a small garden; A white rose flower.

What is encryption? 
In cryptography, encryption is the process of encoding a message or information in such a way that only authorized parties can not access it. Encryption does not itself prevent interference, but denies the intelligible content to a would-be interceptor. In an encryption scheme, the intended information or message, referred to as plaintext, is encrypted using an encryption algorithm. 
For technical reasons, an encryption scheme usually uses a pseudo-random encryption key generated by an algorithm. 
It is in principle possible to decrypt the message without possessing the key, but, for a well-designed encryption scheme, considerable computational resources and skills are required. 
An authorized recipient can easily decrypt the message with the key provided by the originator to recipients but not to unauthorized users. 
in your case "WhiteRose Decryptor" software for safe and complete decryption of all your files and data. 
Any other way?
