secretPhrase is the passphrase of the account generating the token
website is a web site URL for which authorization should be granted, or general text to be digitally signed
Note: website is typically a URL (with the leading http:// unnecessary) that an account owner signs with his secretPhrase (private key) to bind the account to the URL, but website can be any text that the owner wishes to sign.
token (S) is a 160 character string representing the 100-byte token which consists of a 32-byte public key, a 4-byte timestamp, and a 64-byte signature
account (S) is the account number corresponding to secretPhrase
accountRS (S) is the Reed-Solomon address of the account
timestamp (N) is the time (in seconds since the genesis block) that the token was generated
valid (B) is true if token is valid, false otherwise
requestProcessingTime (N) is the API request processing time (in millisec)
Note: Since token contains the token generator's public key and signature, the website can be validated as authorized by the owner of the public key using Decode Token.
