113 | * === EXCERPT FROM RFC 2617 === | |
114 | * The contents of the nonce are implementation dependent. The quality | |
115 | * of the implementation depends on a good choice. A nonce might, for | |
116 | * example, be constructed as the base 64 encoding of | |
26ac0430 | 117 | * |
62e76326 | 118 | * time-stamp H(time-stamp ":" ETag ":" private-key) |
26ac0430 | 119 | * |
62e76326 | 120 | * where time-stamp is a server-generated time or other non-repeating |
121 | * value, ETag is the value of the HTTP ETag header associated with | |
122 | * the requested entity, and private-key is data known only to the | |
123 | * server. With a nonce of this form a server would recalculate the | |
124 | * hash portion after receiving the client authentication header and | |
125 | * reject the request if it did not match the nonce from that header | |
126 | * or if the time-stamp value is not recent enough. In this way the | |
127 | * server can limit the time of the nonce's validity. The inclusion of | |
128 | * the ETag prevents a replay request for an updated version of the | |
129 | * resource. (Note: including the IP address of the client in the | |
130 | * nonce would appear to offer the server the ability to limit the | |
131 | * reuse of the nonce to the same client that originally got it. | |
132 | * However, that would break proxy farms, where requests from a single | |
133 | * user often go through different proxies in the farm. Also, IP | |
134 | * address spoofing is not that hard.) | |
135 | * ==== | |
26ac0430 | 136 | * |
62e76326 | 137 | * Now for my reasoning: |
138 | * We will not accept a unrecognised nonce->we have all recognisable | |
82b045dc | 139 | * nonces stored. If we send out unique base64 encodings we guarantee |
62e76326 | 140 | * that a given nonce applies to only one user (barring attacks or |
141 | * really bad timing with expiry and creation). Using a random | |
142 | * component in the nonce allows us to loop to find a unique nonce. | |
143 | * We use H(nonce_data) so the nonce is meaningless to the reciever. | |
144 | * So our nonce looks like base64(H(timestamp,pointertohash,randomdata)) | |
145 | * And even if our randomness is not very random (probably due to | |
146 | * bad coding on my part) we don't really care - the timestamp and | |
82b045dc | 147 | * memory pointer also guarantee local uniqueness in the input to the hash |
148 | * function. | |
