Under the hood Public-private key cryptography is a class of encryption methods that require the creation of two separate keys; the “private key” known only to the owner, and the “public key” which is known to anyone. It has several useful attributes, the first is the ability of anyone to encrypt data with a public key that can only be decrypted  15 Jan 2016 Think of it as “encrypting” the wires inside of the box in such a way that the encryption cancels itself out and ultimately has no effect on the output, but does have the effect of making it absolutely impossible to see what is going on inside. Unfortunately, absolutely perfect black-box obfuscation is The encryption keys were sent through the Ethereum blockchain with the help of smart contracts. These contracts contained the sender's and receiver's addresses, a key, as well as a link to the publicly-stored document.
