/**
|
||||
*
|
||||
* Magic Auth
|
||||
* ==========
|
||||
*
|
||||
* So-called "magic auth" takes place by a special exchange. On the site where the "channel to be authenticated" lives (e.g. $mysite),
|
||||
* a redirection is made via $mysite/magic to the zot endpoint of the remote site ($remotesite) with special GET parameters.
|
||||
*
|
||||
* The endpoint is typically https://$remotesite/post - or whatever was specified as the callback url in prior communications
|
||||
* (we will bootstrap an address and fetch a zot info packet if possible where no prior communications exist)
|
||||
*
|
||||
* Five GET parameters are supplied:
|
||||
* * auth => the urlencoded webbie (channel@host.domain) of the channel requesting access
|
||||
* * dest => the desired destination URL (urlencoded)
|
||||
* * sec => a random string which is also stored on $mysite for use during the verification phase.
|
||||
* * version => the zot revision
|
||||
* * delegate => optional urlencoded webbie of a local channel to invoke delegation rights for
|
||||
*
|
||||
* * test => (optional 1 or 0 - debugs the authentication exchange and returns a json response instead of redirecting the browser session)
|
||||
*
|
||||
* When this packet is received, an "auth-check" zot message is sent to $mysite.
|
||||
* (e.g. if $_GET['auth'] is foobar@podunk.edu, a zot packet is sent to the podunk.edu zot endpoint, which is typically /post)
|
||||
* If no information has been recorded about the requesting identity a zot information packet will be retrieved before
|
||||
* continuing.
|
||||
*
|
||||
* The sender of this packet is an arbitrary/random site channel. The recipients will be a single recipient corresponding
|
||||
* to the guid and guid_sig we have associated with the requesting auth identity
|
||||
*
|
||||
* \code{.json}
|
||||
* {
|
||||
* "type":"auth_check",
|
||||
* "sender":{
|
||||
* "guid":"kgVFf_...",
|
||||
* "guid_sig":"PT9-TApz...",
|
||||
* "url":"http:\/\/podunk.edu",
|
||||
* "url_sig":"T8Bp7j...",
|
||||
* "sitekey":"aMtgKTiirXrICP..."
|
||||
* },
|
||||
* "recipients":{
|
||||
* {
|
||||
* "guid":"ZHSqb...",
|
||||
* "guid_sig":"JsAAXi..."
|
||||
* }
|
||||
* }
|
||||
* "callback":"\/post",
|
||||
* "version":1,
|
||||
* "secret":"1eaa661",
|
||||
* "secret_sig":"eKV968b1..."
|
||||
* }
|
||||
* \endcode
|
||||
*
|
||||
* auth_check messages MUST use encapsulated encryption. This message is sent to the origination site, which checks the 'secret' to see
|
||||
* if it is the same as the 'sec' which it passed originally. It also checks the secret_sig which is the secret signed by the
|
||||
* destination channel's private key and base64url encoded. If everything checks out, a json packet is returned:
|
||||
*
|
||||
* \code{.json}
|
||||
* {
|
||||
* "success":1,
|
||||
* "confirm":"q0Ysovd1u...",
|
||||
* "service_class":(optional)
|
||||
* "level":(optional)
|
||||
* "DNT": (optional do-not-track - 1 or 0)
|
||||
* }
|
||||
* \endcode
|
||||
*

* @brief zot communications and messaging.
|

*
|
||||
* Sender HTTP posts to this endpoint ($site/post typically) with 'data' parameter set to json zot message packet.
|
||||
* This packet is optionally encrypted, which we will discover if the json has an 'iv' element.
|
||||
* $contents => array( 'alg' => 'aes256cbc', 'iv' => initialisation vector, 'key' => decryption key, 'data' => encrypted data);
|
||||
* $contents->iv and $contents->key are random strings encrypted with this site's RSA public key and then base64url encoded.
|
||||
*
|
||||
* Once decrypted, one will find the normal json_encoded zot message packet.
|
||||
*
|
||||
* Defined packet types are: notify, purge, refresh, force_refresh, auth_check, ping, and pickup
|
||||
*
|
||||
* Standard packet: (used by notify, purge, refresh, force_refresh, and auth_check)

||||
* \code{.json}

|
||||
* }
|
||||
* \endcode
|
||||
*
|
||||
* Signature fields are all signed with the sender channel private key and base64url encoded.
|
||||
* Recipients are arrays of guid and guid_sig, which were previously signed with the recipients private
|
||||
* key and base64url encoded and later obtained via channel discovery. Absence of recipients indicates
|
||||
* a public message or visible to all potential listeners on this site.
|
||||
*
|
||||
* "pickup" packet:
|
||||
* The pickup packet is sent in response to a notify packet from another site
|
||||
* \code{.json}
|

* {
|
||||
* "type":"pickup",
|
||||
* "url":"http:\/\/example.com",

|
||||
* "secret":"1eaa...",
|
||||
* "secret_sig":"O7nB4_..."
|
||||
* }
|
||||
* \endcode
|
||||
*
|
||||
* In the pickup packet, the sig fields correspond to the respective data
|
||||
* element signed with this site's system private key and then base64url encoded.
|
||||
* The "secret" is the same as the original secret from the notify packet.
|
||||
*
|
||||
* If verification is successful, a json structure is returned containing a
|
||||
* success indicator and an array of type 'pickup'.
|
||||
* Each pickup element contains the original notify request and a message field
|
||||
* whose contents are dependent on the message type.
|
||||
*
|
||||
* This JSON array is AES encapsulated using the site public key of the site
|
||||
* that sent the initial zot pickup packet.

* Using the above example, this would be example.com.

|

|

* On receipt of a ping packet a ping response will be returned:
|
||||
*
|
||||
* \code{.json}
|
||||
* {
|
||||
* "success" : 1,
|
||||
* "site" {
|

* "url": "http:\/\/podunk.edu",

||||
* "url_sig": "T8Bp7j5...",

* MIICIjANBgkqhkiG9w0BAQE..."
|
||||
* }
|
||||
* }
|
||||
* \endcode
|
||||
*
|
||||
* The ping packet can be used to verify that a site has not been re-installed, and to
|
||||
* initiate corrective action if it has. The url_sig is signed with the site private key
|
||||
* and base64url encoded - and this should verify with the enclosed sitekey. Failure to
|
||||
* verify indicates the site is corrupt or otherwise unable to communicate using zot.
|
||||
* This return packet is not otherwise verified, so should be compared with other
|
||||
* results obtained from this site which were verified prior to taking action. For instance
|
||||
* if you have one verified result with this signature and key, and other records for this
|
||||
* url which have different signatures and keys, it indicates that the site was re-installed
|
||||
* and corrective action may commence (remove or mark invalid any entries with different
|
||||
* signatures).
|
||||
* If you have no records which match this url_sig and key - no corrective action should
|
||||
* be taken as this packet may have been returned by an imposter.
