hub.secret already specifies a maximum length of "200 bytes".

A maximum length would be nice to define for verify_token, since it needs to be stored by the hub if it's provided.

The previous revision of the spec defined secret and verify_token as 'bytes', and shouldn't be handled with any particular character encoding - they are simply binary data, which the hub shouldn't be paying any attention to the contents of.

Hi there,

I am currently implementing PuSH for Google hub.

I am having an issue with current definition of verify token in parag
6.1. hub.verify_token is defined as "a subscriber-provided opaque
token".  This doesn't specify what an opaque token is in max length,
allowed chars (alphanum only ? more ?), etc.

Wouldn't the spec benefit from those additionals details ? [Unless
"opaque token" is officially defined somewhere else and I missed it]

Same applies to hub.secret.
