This is a key generator. It generates a public/private key pair for cyberway blockchain.
Key is generated from your input. As input can be used any random string, but in order to give a structure, it was splitted into three fields - user name, purpose and password. You can still enter any random characters text there. These fields just a mnemonic and can be used to re-create generated keys, if it is easer for you to remeber username, purpose and password instead of key.
Username and password are NOT related to any account or some thing else. These are just a free text fields.
