Once you've created an account and keypair has been created for it, to now interact with the protocol, to sign messages and transactions you will first have to authenticate. For authentication the flow is more or less the same.
The setup is the same we just call the authenticate function with the userInput.
The authenticate function returns two items, a header which we use to authenticate subsequent requests, and the address associated with the account
The authenticatedHeader
{ // When we call setupEncryption, it generates a random aes key for you. It is the encrypted version of AES key using our public RSA key

Now with these setup, we can start to sign messages and transactions.
