 We also support unsigned plaintext JWTs as introduced by draft 03 by explicitly specifying `nil` as the key and algorithm:
 
-    jwt = JWT.encode({"some" => "payload"}, nil, nil)

     JWT.decode(jwt, nil, nil)
 
 ## Support for reserved claim names
 JSON Web Token defines some reserved claim names and defines how they should be
 used. JWT supports these reserved claim names:
 
- - "exp" (Expiration Time) Claim
- - "nbf" (Not Before Time) Claim
+ - 'exp' (Expiration Time) Claim
+ - 'nbf' (Not Before Time) Claim

 You pass the expiration time as a UTC UNIX timestamp (an int). For example:
 
-    JWT.encode({"exp": 1371720939}, "secret")

 Expiration time is automatically verified in `JWT.decode()` and raises
 `JWT::ExpiredSignature` if the expiration time is in the past:
