CPChain DApp - Identity

Identity DApp is the fundamental DApp of the CPChain DApp Ecosystem. This DApp is used for registering user's public-key and other customize information.

A user generates a pair named private-key and public-key. Then register public-key in the DApp. When someone wants to send a message or file to him, they can get the public-key in Identity DApp, then encrypt the message or file. Finally, send an encrypted message or file to him. The user decrypts a message or file with his private key.

A user also can sign a message or a file with the private-key, then others validate it with the public key got from DApp.
