التشفير

I am a secret so everyone can know me. First you must count every part of me, then translate those parts into signs that do not describe me. Together we are shackled, and with the sign that does not describe me you can open me up and read me as I am. People will give you their promises for me, and if wrongdoers try to take me away from you, you can find me and tell the world where I am hidden. I began as a silent speaking, a key to open every door; now that I have opened all the front doors, I am the key that locks the back doors by which wrongdoers try to escape the scene of the crime. I am the nothing that makes everything happen. You don’t know me, you don’t understand me; and yet still, if you want justice, I will help you to find it. I am blockchain. I am encryption. I am code. Now put me to use.
